To improve SIP signal execution in MANET, routing parameters must be powerfully balanced through SIP methods dependent on a set equal for execution improvement measurements to help the SIP signal framework. In this manner, the presentation of the Optimal Link State Routing Protocol (OLSR) is to be additionally improved. In MANET, vitality is a key anxiety for secure communication, making it conceivable to avoid enemies or childish hubs since the system. In term of this paper, the projected secure as well as QoS based energy aware multipath routing in MANET. In support of multipath path collection, we have provided the Optimal Link State Routing Protocol (OLSR) algorithm. Energy efficient multipath routes are designated on the system using this method. Afterward a quantity of transactions, a route may misplace its connection quality. Hence the optimal path is selected to the paths installed on the system utilizing the Spider Monkey Optimization (SMO) algorithm. At last the presentation measurements of our planned SMO-OLSR task are contrasted and the current OLSR. SMOOLSR used for hybrid wireless network for efficient communication. The reproduction results demonstrate that the presentation of our planned work, the packet delivery rate, the delay, and the packet fallout are improved over the existing work. This planned methodology is actualized on the foundation of NS2

Efficient Operation

Wireless Sensor Networks (WSNs) are emerging network technology with innumerable applications. But security and energy constraints reduce its successful deployments. The nodes in network are greatly involved in transmissions and other processing operations for maintenance other than establishing or handling a call. Due to limited processing ability, storage capacity and most importantly the available battery power of the nodes, it is required to minimize the transmission power and the amount of data transmitted, for efficient operation. This paper presents a power aware routing protocol designed for wireless sensor networks. The proposed routing protocol is an extended and enhanced version of Dynamic Source Routing protocol. It adds energy awareness to the existing implementation of DSR protocol. Energy metric is considered during route selection process to choose an optimal path in terms of overall energy of the nodes along the path, and “low energy notification” method is used during route maintenance process to increase the lifetime of the bridge nodes to avoid network partitioning. The performance of DSR protocol and Energy Aware DSR (EADSR) protocol are compared through NS2 simulation under different scenarios. In all the cases, it is seen that EADSR protocol out-performs DSR protocol by energy saving in efficient manner

In mobile ad hoc networks, nodes are mobile and have limited energy resource that can quickly deplete due to the multi-hop routing activities, which may gradually lead to an un-operational network. In the past decades, the hunt for a reliable and energy-efficient MANET routing protocol has been extensively researched. In this thesis, a novel routing scheme for MANETs (so-called MAntNet) has been proposed, which is based on the AntNet approach. Precisely, the AntNet algorithm is modified in such a way that the routing decisions are facilitated based on the available nodes energy. Additionally, some energy-aware conditions are introduced in MAntNet and replicated in the conventional AODV routing protocol for MANETs. The resulting energy-aware M-AntNet (E-MAntNet) and energy-aware AODV(E-AODV) are analyzed using NS2 simulations. The results show that E-MAntNet performs significantly better than MAntNet and E-AODV both in terms of network residual energy and number of established connections in the network.

A class of networks called VANET(vehicular adhoc network) ,the extension of MANETs(mobile adhoc network) are based on the principle of the formation of wireless network for exchange of data and the creation of network is spontaneous in nature. The mobility constraints, behavior of driver, high speed, limited coverage of wifi, hard delay constraints leads to unique characteristics in VANETS. So the MANET routing protocols are not suitable for VANET. Optimization of routing protocols becomes necessary to make it suitable for VANET. In this paper , various optimized routing protocols are analyzed and their optimization techniques are discussed. Parameters such as end to end delay and energy spent are taken into consideration in order to show the improvement from the routing protocols that are standard protocols. Then a method has been proposed to optimize the fine tuned OLSR (optimized link state routing)protocol with the use of advanced genetic algorithm to further improve the results and to make the protocol more efficient

Save Energy

Energy and security are the two vital components of Mobile Ad-hoc Networks (MANETs). During routing finding an optimal path from sender to receiver sense of path length (number of hops), longevity (battery life) and security becomes an essential requirement. Variety of schemes are proposed by the researchers for finding the shortest path along with energy saving and protecting from attacks Black-hole and gray-hole attacks are some of the most harmful attacks against MANET communication and needs attention. These attacks may cause by insider or outsider malicious node(s) who may drop packets or misroute the information during communication from sender node to receiver node. In our study we proposed an intelligent routing protocol based on Ant Colony Optimization (ACO) technique that finds shortest path from source to destination, applies the concept of power aware techniques to save energy increasing the longevity of the link avoiding link failure and also uses the concept of digital signatures, watchdog and path rater for detection and avoidance ofblack-hole and gray-hole attacks. Simulation study of the proposed scheme is made over some network parameters and found to be efficient in comparison to the basic AODV routing protocol.
