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.

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.
