Coverage Protocol for Wireless Sensor Networks Using Distance Estimates
— In wireless sensor networks, it is desirable to maintain good sensing coverage while keeping the number of active sensor nodes small to achieve long system lifetime. Existing coverage algorithms assume some form of localization and that complete coverage is needed. Our work is motivated by two observations. First, localization is expensive, error-prone and not required for a coverage algorithm. Instead, coverage algorithm can be designed using only distance information between two nodes. Second, complete coverage can lead to excessive redundancy, resulting in inefficiency in terms of active nodes needed. In this paper, we first present a scheme that estimates the distance between any two neighboring nodes using only local information. We then present CCP, a configurable coverage protocol that requires only neighbor distance information. CCP can be configured such that at least α portion of the area will be covered by active nodes with high probability, where α is a tunable pa...
