An Efficient Data Dissemination Mechanism for Wireless Sensor Network with Mobile Sink

This work investigates into the design of sink location propagation in wireless sensor network with mobile sink. In our proposed work, few sensor nodes are assigning a role to propagate the sink location information to the remaining nodes. We refer such nodes as beacon nodes (BNs). We design a distributed algorithm to select BNs. The selection of BNs depends on their sensor node degree. To ensure connectivity among the BNs, we also select few more sensor nodes to act as gateways between the BNs and we refer them beacon gateways (BGs). Combining BNs and BGs leads to formation of backbone network to propagate the sink location. In this project, we compare proposed algorithm a well known data dissemination technique, i.e., flooding. Simulation results show that the proposed algorithm achieves remarkable improvement over flooding in terms of energy consumptions.
