Item A unique method to uniformly distribute the load in LEACH and simulation(2013) Saboo, N.; Bhat, P.P.; Panwar, S.; Yadav, R.; Guddeti, G.A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. Energy efficiency is the important key for WSN. To lower the energy consumption, the network is divided into several clusters in cluster routing algorithm LEACH (Low Energy Adaptive Clustering Hierarchy). Even though clustering provides energy efficiency, but uneven load distribution still occurs in general. In this paper an approach is presented which divides the deployment region into sub-regions and thereby uniformly distributing the load among the sensor nodes. Different shapes are considered for dividing the deployment region into equal sub-regions. The proposed algorithm is known as enhanced LEACH (e-LEACH). © 2013 IEEE.Item Energy efficient LEACH by enhancing the data update procedure of cluster head(2013) Rajan, P.; Geetha, V.There are several modification has been happened in LEACH protocol. Most of modifications are in cluster organization. This paper studies modified LEACH protocol using data update procedure of cluster head. In LEACH protocol frequency of sending data to the base station by smaller cluster is higher than bigger cluster due to that energy dissipation in smaller cluster is more than bigger cluster. This paper studies modified LEACH protocol in which frequency of sending data to the base station by each cluster is same. Simulation has been done in NS2 and simulation result shows that modified LEACH protocol is more energy efficient than LEACH protocol. © 2013 IEEE.Item Baud Rate-Based Hierarchical Multihop Routing Protocol for WSNs(Springer Science and Business Media Deutschland GmbH, 2020) Sowmya, G.V.; Manjappa, M.In wireless sensor networks (WSNs), the data sensed by the sensor node are forwarded to the sink node either by direct communication or by multihop communication. The disadvantage of direct communication is that the sensor nodes consume more energy to reach the sink node as each sensor node has to work alone to reach the sink node, and if the sink node is too far, condition gets worsens. Contrary to direct communication, the multihop communication saves energy as it forwards the data to the nearest neighbor node which in turn forwards the data toward the sink node. In multihop communication, choosing the best neighbor node for forwarding the data is the most challenging task. Hence, in this article, a novel hierarchical multihop routing protocol for WSNs referred to as “Baud Rate-Based Hierarchical Multihop Routing Protocol for WSNs†has been proposed which uses Shannon channel capacity model ‘C’ and neighbor node distance to choose the best neighbor node; the chosen neighbor node will be capable of transmitting data with high baud rate, thereby increasing the throughput of the network. Further, the proposed model also increases the lifetime of the network as the nearest neighbor node will be chosen for the data transfer which saves the energy of the sensor node. The proposed algorithm is compared against the LEACH routing protocol and multihop LEACH protocol and is implemented in MATLAB. The quantitative and qualitative analysis of the simulation results depicts that the proposed algorithm performs better against the parameters remaining energy of the sensor nodes, network lifetime, and data throughput when compared to LEACH and multihop LEACH protocols. © 2020, Springer Nature Singapore Pte Ltd.
