Comparison and Analysis of Node Deployment for Efficient Coverage in Sensor Network
Wireless sensor network (WSN) is composed of sensor nodes, which have capability of perception, computing, sensing, and communication. In wireless sensor network, the number of nodes deployed in a region is directly proportional to the cost of network, performance, and robustness. Sensor node deployment is an essential issue to be resolved in WSNs. A proper node deployment method can reduce the complexity of problems in WSNs. In this paper, we calculate the efficiency of some popular regular deployment patterns such as square grid, triangular lattice, and rhomb in terms of the number of sensors required to provide coverage and connectivity. We have shown comparison between these patterns in terms of total coverage area and net efficient coverage area ratio for varying number of nodes. Simulations have been done using MATLAB R2010a.
