Paper Details

Wireless Sensor Networks are spatially distributed network of autonomous sensors used for monitoring anenvironment. To ensure that in Wireless Sensor Networks, the battery powered Clusters should complete all of its tasks,Network must minimize its use of communication resources as one of major energy costs in WSN is the energy spent oncommunication between nodes and sometimes it is desirable to send data to a gateway node when an event of interest isoccurred at a node [15]. Then sensors will open communication only during a probable event, saving on communicationcosts. Interested fields in this type of network include traffic control, health care, surveillance, home automation, disasterrelief, and more. In this paper we propose modification of Scalable Energy Efficient Clustering Hierarchy (SEECH) [9].The above was designed for sensor networks where they select CHs and relay nodes separately based on the number ofneighbors (degree). Low degree and High degree nodes are employed as relay and cluster head respectively. In thisprotocol data was sensed and information of all nodes are gathered periodically and sent to base station afteraggregation by the CHs. In the proposed protocol(ED-SEECH) the event driven approach is used [1] .Data istransmitted whenever an event is reported. We evaluated the performance of our protocol with MATLAB in two differentnetwork size scenarios and we observed our protocol outperforms the SEECH protocol in terms of energy consumptionand lifetime.
