In wireless sensor networking applications, collecting sensed data and relaying it to the base station in an energy efficient manner is of paramount importance. It follows that power management and energy-efficient communication techniques become necessary to maximize network lifetime for wireless sensor networks (WSNs). In this paper, our objective is to distribute energy consumption evenly and maximize the network lifetime by utilizing data aggregation and in-network compression technique. We mainly focus on the combined problem of data routing with data aggregation during routing such that minimizing the number of packets to transmit and achieve our objective. We propose a multi chain routing algorithm executed with compressive sensing for data aggregating in WSNs. We show that by using our compressive sensing based routing algorithm significant reduction in data traffic can be achieved, resulting in power saving and thus prolong the network lifetime.
