In this paper, we are propose a cluster routing algorithm based on RSSI (Received Signal Strength Indication) for an efficient multi-hop data forwarding. The proposed a cluster routing algorithm determine a header by generate the cluster a random to between nodes of similar positions using the RSSI of each node to the sink node in the cluster-based wireless sensor network. And it are to the data transmission...
Wireless Sensor Networks (WSNs) are a promising technology to monitor distant or inaccessible areas. As nodes have a limited energy supply, many routing protocols are based on a clustering mechanism: some nodes are elected as cluster heads and have to deal with most of the communication burden of the network, while the other nodes perform only simple operations. In this paper, we propose a new election...
Wireless Sensor Networks have been organized for various aspects like, data collection, security, tracking, military applications etc. But one of the major challenges in Wireless Sensor Network (WSN) that is yet to be sorted out is the lack of energy efficiency which retards the lifetime of the network. Clustering or Hierarchical routing is good solution for reducing much of energy consumption in...
Mobile sink is a kind of node with mobility in wireless sensor networks, which is proved to balance the energy consumption of the whole network effectively and solve the "Energy hole" problem.

Information gathering from our surroundings in our absence is an important research topic in recent years. This issue is addressed by WSN(Wireless Sensor Networks) which are more reliable and eliminates the wired network. Sensors(Nodes) are becoming smaller in size and have less cost. These Nodes are powered by non-rechargeable batteries. Therefore Nodes must commission their work with unique initial...
Wireless sensor networks are characterized by their sensitivity to complex routing protocols that waste energy. In fact, many ad hoc protocols were experimentally proven to be inconvenient for this type of networks. MR-LEACH is a protocol that governs the sensors data transfer to the base station in a multi-hop hierarchical manner. However, the hierarchical clustering does not achieve a high performance...
Energy efficiency is resent issue in wireless sensor network (WSN). Hierarchical routing or Clustering is best solution for reducing energy consumption in WSN.

Lots of research is going on CH (cluster head) election algorithm,...
Wireless Sensor Networks is a Wireless network consists of a Base Station (BS) and more number of wireless sensors inorder to monitor temperature, pressure, motion etc., in different environment conditions.

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...
Wireless Sensor Networks (WSNs) typically aggregate sensed events into a sink by Continuous Monitoring (CM) or Event-Detection (ED). Cluster heads receiving and sending aggregated data have a difficulty in maintaining traditional cluster-based WSNs due to the energy hole problem, which leads to faster energy depletion around the sink. This paper shows how reporting frequency to the sink can be controlled...

One of algorithms proposed in this field is DECSA. Aiming at the problem...
In wireless sensor networks (WSNs), reducing sensor node energy consumption and increasing network lifetime are becoming more and more challenging due to large scale. Hierarchical protocols, especially Low Energy Adaptive Clustering Hierarchy (LEACH), are considered as the best energy-efficient for WSNs. However, LEACH need to be enhanced to support scalability in large WSNs. In this paper, we propose...
Wireless communication technologies are used to collect information from sensitive, hostile and inaccessible environments.

Routing data to a processing center or a base station requires mechanisms for energy conservation at the end of the prolonged lifetime of the network. The...
