ABSTRACT
A mobile sensor network is a distributed collection of nodes, each of which has sensing, computing, communicating, and locomotion capabilities. This paper presents a self-deployment obstacle avoidance (SOA) algorithm for mobile sensor networks. The proposed SOA algorithm provides full coverage and can be efficiently used in a complex, unstable, and unknown environment. Moreover, the SOA algorithm is implemented based on the assumption that nodes are randomly deployed near the sink where each node knows the location of the target. In proposed SOA algorithm, the nodes determine a partner node and link up effectively to form a node pair. A node pair which is closest to the target searches for the target with all other node pairs following the previous node. There are number of priority rules on which the mobility of sensor nodes is based. The SOA algorithm ensures that the nodes determine a path around any obstacles. Once a connection is established from the sink to the target, the node pair separates and starts providing the full coverage. The experimental verifications and simulation results demonstrate that the proposed algorithm provides three main advantages. First, it reduces the total computation cost. Second, it increases the stability of the system. Third, it provides greater coverage to unknown and unstable environment.
