Wireless sensor networks (WSNs) distribute hundreds to thousands of inexpensive micro-sensor nodes in their regions, and these nodes are important parts of Internet of Things (IoT). In WSN-assisted IoT, the nodes are resource constrained in many ways, such as storage resources, computing resources, energy resources, and so on. Robust routing protocols are required to maintain a long network lifetime...
Given the fact that LEACH protocol didn't take the residual energy of nodes into account when choosing the cluster heads, which may result in the node with rather low energy to be chosen as a cluster head. Thus, it will cause the cluster created by this low-energy node to be dead at an early stage, which wastes the whole network's resource. Here in this paper, we introduced an energy factor when choosing...
Wireless sensor networks consist of low power lightweight sensor nodes that are often placed remotely for applications like wildlife monitoring, rainforest monitoring, military surveillance, forest fire detection etc. Here energy is a critical issue as nodes cannot be recharged and/or replaced frequently. In this paper we propose an energy efficient hierarchical routing protocol for Wireless Sensor...
Cluster-based Mobile Wireless Sensor Networks (CMWSN) has become promising research domain for researchers in the field of ICT. CMWSN has found its way directly into the real world applications only because of the availability of low-cost Sensor nodes. In the last decade, most of the researchers assumed WSN as a collection of homogeneous and stationary sensor nodes. Mobility and heterogeneity of the...
Due to lack of power source, energy is the key concern area in Wireless Sensor Networks. Maximum energy is used in transmission of data. Many research works have been done to develop routing algorithms to increase the lifetime of a sensor network. Among them clustering based approach is well known for achieving energy efficiency. This paper proposes a new routing strategy based on hierarchical routing...
Due to the limitation of energy, the router protocol of wireless sensor network (WSN) must minimize energy consumption to extend the network lifetime. By analyzing the hierarchical routing low energy adaptive clustering hierarchy (LEACH) in WSN, a protocol is proposed to improve of setting up cluster and data transmission route. A timer is introduced to make sure of electing the optimal sensor node...
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...
Wireless sensor networks have become one of the most tempting networking technologies since it can be deployed without the need of a communication infrastructure. In general, there are some major concerns with this technology. That is, sensor node should have a long lasting system lifetime. And the system should keep the livability of nodes in a received level during the using process. In such systems...
Recently in order to improve the longevity and energy efficiency of WSN (Wireless Sensor Network), widely research have been carried on. Up to the present, many presented methods are based on clustering hierarchical structure. Nevertheless, these protocols don't consider the problem of data sensibility. Based on cluster hierarchical structure, we propose a routing protocol through which each node...
This paper presents a clustering routing protocol for event-driven WSNs with Reduction of Reporting node in each cluster. We demonstrate that decreasing the number of reporting nodes in each cluster; increase the number of reports that need to be sent to the sink in order to achieve the energy efficient and desired information reliability. The algorithm also aims at even energy dissipation among the...
The clustering communication sensor network structure is a main energy efficient communication protocol. The cluster heads collect information transmitted from the cluster members to process the data in the base station far beyond. In this structure, the unstable and unevenly distributed cluster heads can increase power of the network system. In this paper, we propose a energy efficient cluster head...
In this paper, we propose a distributed cluster-based (DCB) algorithm for a long-lived sensor network. DCB achieves good performance in terms of network lifetime by using a efficient energy saving mechanism, which can banlance the energy load to the proper nodes. Simulation results show that DCB outperformances HEED in terms of networks lifetime.
Wireless sensor networks (WSNs) consist of a large number of nodes with limited battery power. Thus, the communication must be designed to conserve the limited energy resources of the nodes. In this paper, we propose a cluster-based multipath delivery scheme, called CMDS, which uses cluster and multipath to improve the capability of load balance, and thus prolonging the network lifetime. Firstly,...
