In the recent past, the wireless technology has grown at a very rapid pace and it has brought a revolution in the field of communication. WSNs are of great importance in building the smart devices and intelligent applications such as smart homes, military surveillance applications, target tracking and structural health monitoring etc. One of the major hardware limitations is limited energy of sensor nodes which has motivated researchers to emphasize on energy efficient communication and this in turn has given a lot of stimulus for the research of energy efficient protocols for MAC and network layer. Further, the cross-layer optimizations have a major impact on network performance metrics like increased energy efficiency, enhanced reliability, reduced delay and increased security as well. In this paper, various energy efficient asynchronous MAC, MIMO-MAC layer routing protocols, analysis, cross layer optimization have been discussed.

Network Upgrade

In smart Industrial Wireless Sensor Networks (IWSNs), sensor nodes usually adopt a programmable technology. These smart devices can obtain new or special functions by reprogramming: they upgrade their soft systems through receiving new version of program codes. If sensor nodes need to be upgraded, the sink node will propagate program code packets to them through “one-to-many” broadcasting, and therefore new capabilities can be obtained, forming the so-called Software Defined Network (SDN). However, due to the high volume of code packet, the constraint energy of sensor node, and the unreliable link quality of wireless network, rapidly broadcasting the code packets to all nodes in network can be a challenge issue. In this paper, a novel Energy-efficient Broadcast scheme with adjustable broadcasting radius is proposed aiming to improve the performance of network upgrade. In our scheme, the nonhotspots sensor nodes take full advantage of their residual energy caused in data collection period to improve the packet reception probability and reduce the broadcasting delay of code packet transmission by enlarging the broadcasting radius, that is, the transmitting power. The theoretical analyses and experimental results show that, compared with previous work, our approach can averagely reduce the Network Upgrade Delay (NUD) by 14.8%–45.2% and simultaneously increase the reliability without harming the lifetime of network.

Internet of Things is a distributed collection of smart devices, where the smart device communicates with each other using Device to Device (D2D communication. Due to the resource constraint nature of IOT, the lightweight communication protocol is needed. Message Querying Telemetry Transport (MQTT) is one of the lightweight communication protocol which employs publish and subscribe method. The most of existing MQTT protocols are vulnerable to Denial of Service attack. In order to overcome the issues of the existing system, in this work a novel lightweight protocol by name EES-MQTT (Energy Efficient and Secured MQTT) is proposed which can be able to provide efficient authentication during data transmission by identifying the intruders and removing the malicious nodes. Moreover, the proposed protocol can be able to provide security with better energy optimization. The feasibility of EES-MQTT is carried out using MQTT.fx simulation tool and the Eclipse Paho. The results from the simulation proves that the EES-MQTT reduces impact of malicious nodes and optimizes the energy consumption during the data transmission.

Ubiquitous smart devices with embedded sensors are paving the way for mobile ad hoc networks (MANETs) that enable users to communicate directly, thereby playing a key role in Smart City and Internet of Things applications. In such smart environments, people with smart devices (nodes) can freely self-organize and form self-configuring MANETs to send and forward data packets to a destination over multiple hops via intermediate nodes. However, the energy consumption during routing remains a challenge in such ensemble mobile environments due to the limited battery capacity of mobile devices. Thus the effectiveness of MANET not only depends on control protocols but also on management of network topology and energy administration. Clustering in MANET is useful to make network more manageable. Many clustering protocols and algorithms are proposed to make network more stable and trusted. In this paper we depict the most prominent factor related to the MANET. The motive of this paper is to perform investigational study  including: routing structure, storage method, overhead, cryptographic authentication and misbehavior of nodes to clearly address  relevant problem in cluster based routing protocol and provide a suitable solution by proposing a energy efficient clustering algorithm named as clustering based energy efficient routing algorithm (CEERA).

Secure Routing Protocol

Due to the advancement of information and communication technologies, the use of Internet of Things (IoT) devices has increased exponentially. In the development of IoT, wireless sensor networks (WSNs) perform a vital part and comprises of low-cost smart devices for information gathering. However, such smart devices have constraints in terms of computation, processing, memory and energy resources. Along with such constraints, one of the fundamental challenges for WSN is to achieve reliability with the security of transmitted data in a vulnerable environment against malicious nodes. This paper aims to develop an energy-efficient and secure routing protocol (ESR) for intrusion avoidance in IoT based on WSN to increase the network period and data trustworthiness. Firstly, the proposed protocol creates different energy-efficient clusters based on the intrinsic qualities of nodes. Secondly, based on the (k,n) threshold-based Shamir secret sharing scheme, the reliability and security of the sensory information among the base station (BS) and cluster head are achieved. The proposed security scheme presents a light-weight solution to cope with intrusions generated by malicious nodes. The experimental results using the network simulator (NS-2) demonstrate that the proposed routing protocol achieved improvement in terms of network lifetime as 37%, average end-to-end delay as 24%, packet delivery ratio as 30%, average communication cost as 29%, network overhead as 28% and the frequency of route re-discoveries as 38% when compared with the existing work under dynamic network topologies.
