The connected sensor cover problem: Given a query over a sensor network, select a minimum or nearly minimum set of sensors, called connected sensor cover, such that the selected sensors cover the query region, and form a connected network among themselves. In its general form, this problem is known to be NP-hard; In this thesis research, we design the first, fully distributed, strictly localized, scalable, and self-* solution to the connected sensor cover problem. The Self-* concept has been used to include many fault-tolerant properties like self-configuring , self-reconfiguring/self-healing, etc. We will present a self-stabilizing solution and show that this solution is both self-configuring and self-healing. In a self-stabilizing system, every computation, starting from an arbitrary state, eventually reaches a state which satisfies the specification. Nodes achieve the global objective by using only local computations. Local algorithm based sensor networks are more robust, and scale better. (Abstract shortened by UMI.).
