An Efficient Tree based Topology for Data Collection and Aggregation in Wireless Sensor Network

One of the most important applications of wireless sensor networks is data collection. In Wireless sensor networks (WSNs), users may want to continuously extract data from the networks. But energy efficient data collection and aggregation in wireless sensor network is always a challenging issue. The network topology and interferences also causes significant effects on data collection and aggregation. In this paper, we propose to use multifrequency in channel assignment because scheduling a transmission using multiple numbers of frequencies is more efficient when compared with single frequency. In proposed system, power control helps in reducing the schedule length and multi-frequency scheduling can also suffice to eliminate most of the interference. Our proposed system achieve improvised performance in scheduling e over different utilization densities, determine the impact of different interference and channel models on the schedule length, is to increase the efficiency of data collection using in wireless sensor network.
