In wireless sensor Networks, sending data consumes energy which affects the lifetime of the network. Since Routing protocol plays an important role in this process, designing a routing protocol must take into a count energy consumption in order to increase the lifetime of the network. In this paper, we propose an improved multipath leach protocol which uses at most one intermediate cluster head. The...
Wireless sensor based communication system is an ever growing sector in the industry of communication. Wireless infrastructure is a network that enables correspondence between various devices associated through a infrastructure protocol. In WSN enhancing the life span of network depends on the energy dissipation of the sensor devices. Reducing the energy dissipation of sensor devices will improve...
Wireless Sensor Network (WSN) is structure less platform which consists of multiple number of small sensing, computing capable nodes. WSN facilitate monitoring and detecting physical condition of any environment using sensors. Each sensor is managed with limited battery backup and hence lifetime of the overall system becomes very less. In modern scenario, it's very challenging to prolong the network...

In which separation of the sensor nodes based on their location given by the node electronics using GPS, into certain regions are classified. Sink node (base station) is established away from the sensing region and a gateway node at the middle of sensing region. If the distance of sensor nodes from sink node and gateway node...
In WSN there is always a scope of improvement in efficient energy utilization, network lifetime. Efficient energy utilization always seems to be an important aspect in WSN's. Because of the fact that energy consumption directly effect the overall performance of WSN.

A synchronized network time is always necessary for scheduling to achieve energy efficiency, data fusion, localization for WSN applications. The major limitation in a WSN is the battery usage and lifetime of the nodes. Due to the power restriction of nodes, efficient routing is very important to save the battery of sensors to enhance the lifetime of the sensor area. The multi-head chain concept is...
WSNs have a wide variety of applications, and their usability for remote monitoring of various parameters of interest is growing dramatically. Conventional applications mostly involved a single WSN for collecting raw parameters with limited aggregation on the node side, whereby more sophisticated data mining was implemented by the end-users. Recent applications however, often require more intelligent...
Wireless sensor networks consist of small battery powered devices with limited energy resources. The small sensor nodes are usually inaccessible to the users due to their remote deployment. Non functioning of any sensor due to its loss of battery power not only deteriorates the network performance but also a challenging job for replacement of energy source. Hence, energy efficiency is a key design...
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. Number of sensor nodes located geographically nearer to form a group called cluster to co-operately processing the data. LEACH (Low Energy Adaptive Clustering Hierarchy) is a routing protocol for...
The requirement for operation with low energy consumption is one of the major constraints that guide the design of routing protocol in Wireless Sensor Networks (WSN) because each node is powered by a limited and generally an irreplaceable source of energy. In this context, we would like to propose a new protocol which respects the energy constraints, nodes' life duration and packets reception. This...
Wireless sensor networks are collections of tiny sensors working collaboratively to gather information. Two major shortcomings of today's WSNs are scarce energy and memory resources making it difficult to devise robust and effective security measures. Keyed-hash chains have been proposed as an efficient solution. Nevertheless, the basic configuration of one-way hash chains, where a shared key is hashed...

Several applications in wireless sensor networks require a bidirectional communication between the sensing nodes and the sink. A number of relay nodes is used to achieve this bidirectional communication. The relay nodes adjust their communication range in order to consume less energy, constructing an asymmetric network with unidirectional links.
