Energy consumption problem is considered an extremely important problem that faces the Wireless Sensor Networks (WSNs). For this reason, a lot of efficient energy protocols have been developed in order to reduce the energy consumption, as well as to prolong the lifetime of the sensor networks. The DMHT-LEACH protocol is one of these protocols. It proposes a dynamic technique for facilitating the data...
Even after 16 years of existence, low energy adaptive clustering hierarchy (LEACH) protocol is still gaining the attention of the research community working in the area of wireless sensor network (WSN). This itself shows the importance of this protocol. Researchers have come up with various and diverse modifications of the LEACH protocol. Successors of LEACH protocol are now available from single...
This paper elucidates an Energy Efficient Cluster Based Routing Protocol (EECBRP) for wireless sensor networks. It accomplishes ameliorate performance by means of network lifetime and energy efficiency. It is used to pile up data from scattered sensor nodes and transmit the same to a base station. EEBCRP is designed to shore up the remote monitoring in sensor networks, periodically. Major issues here...
Wireless sensor network is a wireless network consisting of independent sensor, communicating with each other in distributed fashion to monitor the environment. Sensors are usually attached to microcontroller and are powered by battery. The goal of Wireless sensor network is to have long life time and high reliability with maximum coverage. Routing techniques are the most important issue for networks...
In many typical wireless sensor networks, the nodes are fixed, where cluster based protocols like LEACH were suitable for routing. However, it is another story when the nodes are mobile. This paper proposes a novel routing protocol supporting node mobility called “2L-LEACH-M”, it divides the nodes into two levels: level 1 (cluster-head level) or level 0 (member level), which makes mobile nodes find...
In this paper, we present a Multi-hop Routing with Low Energy Adaptive Clustering Hierarchy (MR-LEACH) protocol. In order to prolong the lifetime of Wireless Sensor Network (WSN), MR-LEACH partitions the network into different layers of clusters. Cluster heads in each layer collaborates with the adjacent layers to transmit sensor's data to the base station. Ordinary sensor nodes join cluster heads...
The wireless communication technologies, such as wireless sensor network, can bring great economic benefits to industrial plants. But the open channel and multi-hop network topology will influence its real-time and reliable performance. Funneling effect is a kind of congestion caused by the wireless hop-by-hop and many-to-one networks. IEEE802.15.4 is a wireless personal area network standard that...
We consider a wireless sensor network in which a routing tree has been established to transmit the information from a set of source nodes to a data sink. The existing algorithms to schedule the transmission slots in a way that allows the data to be compressed as it moves towards the data sink are centralized or rely on interference models that fail occasionally. We propose a distributed TDMA scheduling...
In wireless sensor networks, the routing algorithms currently available assume that the sensor nodes are stationary. Therefore when mobility modulation is applied to the wireless sensor networks, most of the current routing algorithms suffer from performance degradation. The path breaks in mobile wireless networks are due to the movement of mobile nodes, node failure, channel fading and shadowing...
This paper addresses the trend in wireless sensor network applications of increasing node density and multi-hop communications that result into extremely challenging design constraints. SSAS, an adaptive hybrid localised sink-oriented Routing/MAC protocol is proposed. It offers a self-configuration scalable solution for large random sensor networks and attempts to alleviate multi-hop congestion problems...
As many routing protocols for wireless sensor network canpsilat handle dynamic topological variation efficiently, a new hierarchical routing protocol (HTVRP) based on the shortest path is proposed. In this protocol, all of nodes are arranged to different logic layers according to their distance from the sink, thus a ring-hierarchy, tree-framework topology is formed. Each node merely communicates with...
