Energy-Efficiency and Reliable Protocol based on Virtual Zones Infrastructure for Wireless Sensor Networks (ERVM)

The field of wireless sensor networks has covered up a large part in the various aspects of scientific research, thanks to its applications that operate in most active domains, such as military purposes, medical and industrial goals. Large scale sensor networks generally consist of hundreds or even thousands of sensor nodes. Establishing a routing process to produce global coverage of a monitored area is the biggest challenge, since the implementation of energy efficiency of wireless communications in each sensor node is critical. Each routing protocol designed for WSN should be reliable, efficient and ensures the increase of the life time of the network. In this paper we present a new routing protocol that supports reliability and energy efficiency ERVM, we evaluate this protocol with a set of existing routing protocols (ZHLS and RZRP ). ERVM considers the residual battery capacity of each sensor node to establish routing paths and to offer the optimal path between several sensor nodes in some specific cases. The evaluation results show the effectiveness of the VZP protocol in terms of end to end delay, and in terms of the number of delivered packets and energy-efficiency.
