HeteRBar: Construction of Heterogeneous Reinforced Barrier in Wireless Sensor Networks

Recently, a barrier-coverage has gained much interest due to potentiality of various applications. In this letter, we introduce a reinforced barrier-coverage in heterogeneous wireless sensor networks, which guarantees that any penetration variation of intruder is detected by at least one sensor with a consideration of heterogeneous sensors with different capabilities. Also, we formally define a problem whose objective is to maximize the lifetime of heterogeneous reinforced barriers and propose two novel approaches, including a creation of base graph. Then, the performances of the proposed schemes are analyzed through various scenarios.
