    Behavior analysis of LEACH protocol
    (Institute of Electrical and Electronics Engineers Inc., 2014) Maurya, Prashant; Kaur, Amanpreet; Choudhary, Rohit
    A wireless sensor network (WSN) is an emerging field comprising of sensor nodes with limited resources like power, memory etc. It is used to monitor the remote areas where recharging or replacing the battery power of sensor nodes is not possible. So, energy is a most challenging issue in case of WSN. Low-Energy Adaptive Clustering Hierarchy (LEACH) is the first significant protocol which consumes less amount of energy while routing the data to the base station. In this paper LEACH protocol has been analyzed with different percentage of cluster heads at different locations of base station in the network. ? 2014 IEEE.

    Segregated receive and relay scheme for communication in wireless sensor networks
    (Institute of Electrical and Electronics Engineers Inc., 2015) Saini, S.; Khurana, S.S.
    A Wireless Sensor Network (WSN) is a set of self-powered sensor nodes. These nodes are deployed in infrastructure less mode to collect the useful information from the environment and transmit it to the sink node. The significance of Wireless Sensor Networks has been evidenced in many applications like military areas, health monitoring and observation of earthquake etc. However, WSN has also some limitations including limited energy supply that leads to shorter life time of the network. Although numerous techniques have been proposed to improve the life time of sensor nodes, yet the large energy requirements for communication activities is still a serious issue. In this work, Segregated Receive and Relay (SRR) based routing scheme has been proposed to increase the lifetime of WSN. To achieve the purpose, relay nodes have been introduced in interior regions of the network area. The results confirm that proposed scheme significantly reduce the energy consumed by interior region nodes, which proves the usefulness of the proposed scheme in prolonging WSN lifetime. ? 2014 IEEE.
