An efficient technique for maximization of network lifetime & minimization of delay for the performance enhancement of WSN

 Abstract— The Main emphasis of this paper is to analyze and assess the performance of various techniques in the effort to determine the maximum lifetime of the nodes & minimization of delay. This paper,mainly concentrate about the two performance metrics parameter which is important to make the WSN as effective as possible ie maximization of network lifetime parameter and minimization of delay for the wireless sensor network. Due to energy limitation of sensors, maximization of lifetime is the key to performance of WSN routing protocol. In such systems mostly energy is consumed when communication radios are on. So sleep-wake scheduling is effective mechanism to increase network lifetime. Sleep-wake scheduling is efficient to increase network lifetime but it could result in substantial delays because a transmitting node needs to wait for its next-hop relay node to wake up. We attempts to reduce these delays by developing ―anycast‖-based packet forwarding schemes, where each node opportunistically forwards a packet to the first neighboring node that wakes up among multiple candidate nodes such set of nodes called forwarding node set. We used anycast forwarding schemes to forward the data packet to next hop node which minimizes the expected packet-delivery delays from the sensor nodes to the sink node. Based on this result, we provide a solution to the problem of how to optimally control the system parameters of the sleep-wake scheduling protocol and the anycast packet forwarding protocol to maximize the network lifetime and minimize the delay with constraint on the expected end-to-end packet-delivery delay. In this paper an in depth analysis has been made to find out the work which is done related to this field.
