Cost Effective Energy Aware Coverage Preserving Protocol for Wireless Sensor Network

[email protected] [email protected] Abstract— Wireless sensor networks are formed by small sensor nodes communicating over wireless links without using a fixed network infrastructure. Each of the sensor nodes is capable of sensing, processing, and transmitting environmental information. Since the sensor nodes are equipped with battery having limited energy, energy efficient information processing is of critical importance. The important issues of wireless sensor networks (WSNs includes Coverage-preserving and lifetime-durability. Any coverage hole in a network is not feasible, so to provide full sensing coverage in a security-sensitive area is necessary in many practical applications such as security surveillances or military investigations. The routing protocols were proposed to ensure reliable multi-hop communication, in order to increase lifetime and Quality of Service (QoS) of wireless sensor networks.
