Abstract
In this thesis, we design the sensor deployment algorithm with the consideration of sensing lifetime for wireless sensor works, which is called lifetime-based deployment algorithm. With uniform sensor deployment distribution, based on different routing protocol could let sensors’ energy consumption at variance. Some sensors maybe die very soon and decrease sensing coverage because they must relay more information or their transmission range is larger. In order to avoid this situation, we deploy more sensors in this area and let sensors deployed in this area die later to maintain total sensing coverage. Our main objective is to propose new methods to search the optimum sensor deployment density based on different routing protocol, multi-hop and LEACH. Use an information outlook to calculate sensors’ energy consumption deployed in every belt with different distance from the server. According to the accumulated information flow, we can search the deployment density in every belt with different routing protocols. Simulation results show that our methods can maintain initial sensing coverage longer than uniform distribution.
