Coverage and energy efficient of mobile wirelees sensor network

Due to recent technological advances, the manufacturing of small and low cost sensors became technically and economically feasible. The sensing electronics measure ambient conditions related to the environment surrounding the sensor and transform them intIn this thesis, we designed a number of algorithms for the following problems in MobileWireless Sensor Network(MWSN):1. Relocation problem in MWSN: we proposed two new algorithms, the first one is to findiiif a sensor is completely covered by its neighbors so as to decide whether it is redundant, and can be used to replace failed nodes. The second algorithm is to relocate the failed node by a proper one. Simulation results show that the redundant discovery 2. Localization problem in MWSN: we introduce a new technique to localize mobile sensor nodes using sectorized antenna. We consider that both nodes and seeds are mobile, and argue that mobility can be exploited to improve the accuracy and precision of loc3. Routing Problem in MWSN: we proposed a new mechanism to gather data using clusters based approach for scalability and a prediction in Disjoint Mobile Wireless Sensor Network(DMSN). The mechanism includes two new centralized and distributed routing disc
