Wireless Sensor Network, or WSN, has a large amount of applications such as target tracking, health monitoring and security etc. These applications have been proposed for mobile wireless Sensor Network (MWSN). Mobile Sensor node transmits the data with a fixed node in real time applications. MWSN uses various handover techniques which support the mobility of different coordinators. IEEE 802.15....

In this paper, we propose a mobile physiological sensor that works with an indoor positioning system based on a wireless sensor network. The physiological sensor is a small, mobile, multi-sensor device which includes electrocardiograph, 3-axis accelerometer, barometer, thermometer, and hygrometer. In addition, the device is a network node of a wireless sensor network and receives beacon signals...

a wireless sensor network consists of many inexpensive sensor nodes that can be used toconfidently extract data from the environment .nodes are organized into clusters and in each cluster all non-cluster nodes transmit their data only to the cluster-head .the cluster-head transmits all received data to the base station .because of energy limitation in sensor nodes and energy reduction in each d...

Wireless sensor networks are the grouping of tiny sensor nodes, which collects the information by sensing activeness from the surroundings similar lands, forests, hills, sea. In wireless sensor networks, using mobile sinks mobility rather than static sink for data collection is the new trend in present years. Current researches are focusing on moving patterns of the mobile sink to achieve optim...

Abstract: Mobile ad hoc network is a collection of wireless mobile hosts which are interconnected by a communication media like radio. The communication network is formed without the aid of any centralized authority or preexisting infrastructure. By its characteristic this type of network is self-starting and self-organizing. It has been observed that mobile ad hoc networks can be exploited for...

A Mobile Wireless Sensor Network (M-WSN) derives its name by considering either mobile sink or mobile sensor nodes within the Wireless Sensor Network (WSN). As the sensor nodes are energy constrained, energy efficiency is the main aspect to be considered in any applications. By considering mobile sensor nodes in WSN, we can have better energy efficiency, improved coverage, and enhanced target t...

mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...

Sensor random locations and sensor failures can cause coverage holes, routing voids and disconnections and thus degrade sensor network performance. In this paper, we present a self-healing approach that utilises a few mobile sensors to deal with the problems. A mobile sensor can move to an area with a coverage hole or routing void and significantly improve network performance. We design distrib...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...
