Abstract

Energy imbalance is a serious problem in wireless sensor network. This paper describes the various reasons for energy imbalance in wsn and different techniques to ensure energy efficient data transmission. It is characterized by multihop routing and difference in the responsibilities of different nodes. So because of different responsibilities, node dissipates their energy unevenly and result into energy holes. These energy holes result into network disconnectivity. So far so many different techniques has been proposed and some of them are exceptionally better than other, but on cost of some parameters and compromising with other parameters.

Abstract

Multi-hop wireless sensor networks are designed for environment surveillance, wherein sensor nodes are deployed in a special environment and are powered by a limited battery. The lifetime of a multi-hop WSN depends on the durability of the sensor nodes battery resources. In this paper, we proposed the designing of a new MAC protocol that allowing the sensor nodes to sleep more under light loads for conserves energy in a multi-hop WSN. The concept of our protocol is quorumbased mechanism and analytical model that can accurately estimating the per-sensor node communication traffic-load of a sensor node. We consider a scenario, wherein the sensor nodes periodically sense the environment and forward the collected data to a sink using greedy geographic routing protocol. We evaluate our implementation of MAC protocol in NS-2. The simulation results showed that our MAC protocol conserved more energy with the low transmission latency and significantly prolong the lifetime of a multi-hop WSNs.
