Geography-informed sleep scheduled and chaining based energy efficient data routing in WSN

We introduce Geography-Informed Sleep Scheduling and Chaining Based Routing (GSSC) algorithm in wireless sensor network. Since sensor nodes are energy constraint, so our aim is to maximize the network lifetime by utilizing the energy of nodes very efficiently. GSSC conserves energy by finding out equivalent nodes from routing perspective by using their geographical information i.e. the nodes which sense almost same information and then turning off unnecessary nodes to remove data redundancy. To further reduce the energy consumption of communication in network we use chaining based routing scheme to route the sensed data from active nodes to the base station. This chaining based data routing can reduce energy consumption of data transmission with the help of multi-hop routing concept. Our simulation results (using MATLAB) show that in comparison of very famous routing protocols like LEACH and PEGASIS, this algorithm has achieved significant increment in network lifetime.
