Research on relationship between memory scale and lifetime of WSNs with cluster mechanism

As the reason that WSNs are critical limited by energy supplication, it becomes the first to all problems that how to prolong the lifetime of WSNs. Cluster mechanism is an efficient method to prolong the lifetime of WSNs by separating WSNs into many clusters. In every turn, each cluster has a head to allocate the data transmitting work. In this paper, we present a research on the affection of memory scale of nodes deployed in WSNs. We use different values of memory scale to test the cluster mechanism deployed in WSNs. Results show that with the increase of memory scale value the lifetime of WSNs has the tendency of more longer existing period. Well, when the memory scale is the integral multiple of 10, such as 10, 20, 30, etc., the lifetime will be the minimal value. This paper gives a quantitative analysis of the relation between length of memory scale and lifetime in WSNs with cluster mechanism.
