Adaptive energy aware cluster-based routing protocol for wireless sensor networks

Wireless Sensor Networks (WSNs) continue to provide essential services for various applications such as surveillance, data gathering, and data transmission from the hazardous environments to safer destinations. This has been enhanced by the energy-efficient routing protocols that are mostly designed for such purposes. Gateway-based Energy-Aware Multi-hop Routing protocol (MGEAR) is one of the homogenous routing schemes that was recently designed to more efficiently reduce the energy consumption of distant nodes. However, it has been found that the protocol has a high energy consumption rate, lower stability period, less data transmission to the Base station (BS). In this paper, an enhanced Heterogeneous Gateway-based Energy-Aware multi-hop routing protocol ( HMGEAR) is proposed. The proposed routing scheme is based on the introduction of heterogeneous nodes in the existing scheme, selection of the head based on the residual energy, introduction of multi-hop communication strategy in all the regions of the network, and implementation of energy hole elimination technique. Results show that the proposed routing scheme outperforms two existing ones.

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 â€œlow energy notificationâ€ 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
