Preusing of influence parameters in Clustered networks by using of Multihop strategy

چکیده مقاله

Wireless Sensor Networks (WSNs) consist of many nodes that sense phenomena in different environments. WSNs are used for many application such as military and battlefield monitoring and home sentry systems. These networks have many constraints like as memory limitation, computing power and energy power. Batteries supply energy power of sensor nodes but they cannot be replaced by new one. So that energy consumption is one of the important challenges in WSN. Clustering is a proper strategy for decreasing energy consumption. HEED is a clustering algorithm that uses a hybrid of energy and communication cost for selecting cluster heads. In this paper, we evaluate different factors in HEED algorithm by using of multi-hop that each node send reading data to the base station which is called sink. Some of effective factors in network lifetime are sink location, initial energy and radio range of each node. Simulation results have shown sink location has more effect in network lifetime.
