ENERGY AND DELAY REDUCTION ALGORITHM FOR CLUSTER BASED CONGESTION CONTROL IN WIRELESS SENSOR NETWORKS

In Wireless Sensor Networks (WSN), delay has be reduced in delay sensitive applications at cost of increased energy consumption, since there is a tradeoff between delay and energy consumption in WSN. But most of works in WSN focus on reducing the energy rather than the delay. Hence the main aim of this work is to reduce both the delay and energy consumption in delay sensitive applications of WSN. In this paper, an efficient energy and delay reduction technique for cluster based congestion control model is proposed. In this technique, the cluster head (CH) is elected based on the energy level of the node. Each cluster member transmit the data and its remaining energy information to the corresponding cluster head as per the given time slot schedule. The delay in data transmission can be reduced by adaptively adjusting the active mode of the node based on the congestion status and distance of node. By simulation results, we show that the proposed technique reduces the energy consumption and delay of highly loaded sensor nodes.
