Energy-efficient Multilevel Heterogeneous Routing Protocol For Wireless Sensor Networks

Energy-efficient Multilevel Heterogeneous Routing Protocol for Wireless Sensor Networks

Abstract:

Wireless sensor Networks (WSNs) are being applied widely for data collection, especially to carry out the mission critical tasks. Therefore, one of the most challenging tasks of Mission critical Sensors and device Networks (MC-SSN) is the development of energy efficient (EE) routing protocols. Comparing with flat routing protocols, more electrical engineering can be achieved in hierarchical routing protocols. During this, we propose an enhanced balanced energy efficient network-integrated super-heterogeneous (E-BEENISH) routing protocol, by analyzing communication energy consumption of the clusters and large range of energy levels in heterogeneous WSNs. E-BEENISH is based on weighted election probabilities of each node to become a cluster head (CH) according to the remaining energy and the distance from the sink to node. Moreover, we also study the impact of heterogeneity of nodes in terms of energy. Finding out the sensitivity of our stable election protocol, we conclude heterogeneity parameters capturing energy imbalance in the network, and notice that E-BEENISH yields the longer stability region for suitable weight of energy and distance. Our results show by simulation that E-BEENISH will improve system lifetime by an order of magnitude compared to obtained using current clustering protocols, which is crucial for several applications.
