Abstract

The objective of this work is to maximize the network lifetime by utilizing data aggregation and in-network processing techniques. Here, data aggregation and data routing is addressed as joint problem to achieve the objective. This paper considers the problem of correlated data gathering in WSNs with the objective of minimizing the total transmission cost in terms of power consumption. To minimize the energy consumption, two-level aggregation in fixed virtual grid is used. The first level aggregation is within the cluster by using cluster head and second level aggregation is from the set of cluster heads to group aggregators. In this paper mainly focused on the problem of finding the set of aggregation points that satisfy the objective. Fixed virtual wireless backbone that is built on top of the physical topology is used to reduce clustering and routing overhead. Numerical results show that the proposed work provides substantial energy savings.
