A novel algorithm for traffic reduction in wireless sensor networks

In Wireless Sensor Network, the communication generally takes higher energy than other operations like sensing and data processing. So the traffic reduction in communication is one of the most important concern for prolong the life of sensors. This paper presents three traffic reduction techniques based on dominating set. In the first approach base station is dynamically relocate to the sensing area in which heavy packet traffic. The selection of base station depends on various performance metrics such as energy, signal strength and the location of the selected node. The second approach intelligently distributes the burden of broadcasting process by applying the concept of localized domination set based multicast. In the third approach i.e., Dominant Set Pruning (DSP) is used to avoid unnecessary control packet flooding in sensor network The efficiency of dominant-set-based broadcasting or routing mainly depends on the overhead in constructing the Connected Dominating Set (CDS) and the size of the dominating set. The paper proposes a novel algorithm for determine the CDS with less computation complexity. The performance of the algorithm is evaluated by using simulation. The modified algorithm has a tremendous reduction in traffic than the existing AODV algorithm.
