Abstract
A mobile wireless sensor network owes its name to the presence of mobile sink or sensor nodes within the network. The advantages of mobile WSN over static WSN are better energy efficiency, improved coverage, enhanced target tracking and superior channel capacity.
Recent advancements in technology have made low-cost, low power wireless sensors a reality. A network of such nodes can coordinate among themselves for distributed sensing and processing of certain phenomena. In this project a protocol to provide a stateless solution in sensor networks for lifetime maximization is proposed. The protocol proposes a unique way to maximize the life time. Lifetime maximization is one key element in the design of sensor- network-based surveillance applications. A protocol for node sleep scheduling that guarantees a bounded-delay sensing coverage while maximizing network lifetime is proposed. The detection of rare events, where the network is normally silent, except when an event occurs is focused. Sleep scheduling ensures that coverage rotates such that each point in the environment is sensed within some finite interval of time, called the detection delay.
