ABSTRACT This paper studies LEACH protocol, and puts forward energy-LEACH and multihop-LEACH protocols. Energy-LEACH protocol improves the choice method of the cluster head, makes some nodes which have more residual energy as cluster heads in next round. Multihop-LEACH protocol improves communication mode from single hop to multi-hop between cluster head and sink. Simulation results show that energy-LEACH and multihop-LEACH protocols have better performance than LEACH protocols.

    ABSTRACT: Cluster based routing protocols have significant impact on the energy dissipation and life time of wireless sensor networks (WSN). In this paper Basic Low Energy adaptive clustering hierarchy (LEACH) protocol has been modified with our proposed LEACH-MAE(LEACH-Mobile Average Energy based) protocol to overcome its shortcomings to support mobility along with the new average energy based Cluster Head selection technique. Our simulation in NS2 shows that proposed algorithm improves network life time up to 25 % as well as helps to maintain the equal distribution of energy resource among the sensor nodes.

    ABSTRACT: Due to the big and essential role played by the cluster head in hierarchical protocols of wireless sensor network, it consumes an amount of energy more than the member nodes of the cluster. Therefore, the hierarchical protocols usually suffer from a packet loss due to frequent cluster head failure during the data transmission. This decreases the communication reliability in wireless sensor network applications. Errors caused by data loss inevitably affect the data analysis and subsequent decision making. This paper introduces, the Low-Loss Low-Energy Adaptive Clustering Hierarchy Centralized Protocol (LLEACH-C); LLEACH-C provides a cluster head recovery mechanism, which recovers the cluster head's death during the protocol round operation. This is a missing mechanism in LEACH-C protocol, the protocol that is one of the most popular in hierarchical protocols. The simulation results showed that, LLEACH-C succeeds in decreasing the data packet loss by on average 43% over LEACH-C, and in increasing the lifetime of the network by on average 69.3% more than VLEACH, the protocol that also proposes a mechanism for cluster head death recovery. Furthermore the behavior of the LLEACH-C, in both of the End to End delay and Throughput, are analyzed and compared to VLEACH.

    ABSTRACT: Wireless sensors networks consist of a number of sensors nodes connected through a wireless network that collect data to be treated locally or relayed to the sink node using multi-hop wireless transmission. Several solutions were pro-posed to minimize the amount of information flowing within the network. Clustering algorithms is one solution and mechanism that enables the creation of sensor's clusters; each sensor is dominated by elected routers. In order to limit energy consumption, the clustering around the sensor is established: sensors linked to the router transmit relayed data thereafter outward. The number of messages sent and the transmission range are thus reduced. This article tackles this issue by unveiling proposed techniques in the same line of researches and proposing a clustering mechanism based on the amount of energy remaining in the sensors. The simulation results show that proposed method can achieve higher network lifetime by comparison to original LEACH.
