This paper introduces a new maximum fault-tolerance barrier-coverage problem in hybrid sensor network, which consists of a number of both static ground sensors and fully-controllable mobile sensors. The problem aims to relocate the mobile sensor nodes so that the fault-tolerance of the barriercoverage of the hybrid sensor network is maximized. The main contribution of this paper is the polynomi...

This type of network can truly implement the goal of providing health-care services anytime and anywhere. Our research in this field generates the following outcomes that are reported in this pap...

The effectiveness of a distributed self organizing Mobile Wireless sensor Network depends to a large extent on coverage provided by the sensor deployment. Mainly this paper considers the fundamental problems of a dynamic sensor network, THE COVERAGE. Localization of mobile sensors is a challenging issue, and the same is solved by developing a spatial addressing scheme for mobile sensor networks...

Routing protocol for wireless mobile sensor networks can be active, can also be passive. The network all wireless sensor node is base station and the gateway for two-way communication. To complete the training parameters, which can be called the training function is used to train the BP neural network. The paper presents design and implementation of wireless sensor network nodes based on BP neu...

Mobile wireless sensor network (MWSN) is a wireless ad hoc network that consists of a very large number of tiny sensor nodes communicating with each other in which sensor nodes are either equipped with motors for active mobility or attached to mobile objects for passive mobility. A real-time routing protocol for MWSN is an exciting area of research because messages in the network are delivered ...

A Wireless Sensor Network applications include a set of isolated urban areas deployed with sensor nodes for monitoring environmental parameters. In urban area vehicles viz (buses, vans, cars, etc) are used as to carry the mobile sinks to collect the sensory data effectively which provides the ideal infrastructure. Existing approach include only single hop transfer, which transfer data directly ...

Sensor networks may be deployment in hostile environments, especially in military applications. Small low cost sensor devices each equipped with limited resources are networked and are used for various critical applications. Making such sensor network secure is a challenging issue. Under such situations, the sensors may be captured, and the data may be intercepted and/or modified by the attacke...

In this paper, we intend to focus on the sensor network applications in firefighting. A distributed algorithm is developed for the sensor network to guide firefighters through a burning area. The sensor network models the danger of the area under coverage as obstacles, and has the property to adapt itself against possible changes. The protocol developed, will integrate the artificial potential ...

Mobile autonomous platforms are considered as mobile nodes in a collaborative wireless sensor network to estimate environmental parameters like temperature, humidity, pressure, sunlight and position. These small robots are equipped with cheap and energy efficient sensory module, based on MTS420 environmental sensor board. For a better approximation of the reality, statistical indicators like sa...

Formally, given a set of n homogenous or heterogeneous mobile sensors {s1, s2, ..., sn} that are capable to acquire m physical attributes {a1, a2, ..., am} from their environment at every discrete time instance t (i.e., data has a temporal dimension), an implicit or explicit mechanism that enables each si (i ≤ n) to move in some multi-dimensional Euclidean space (i.e., data has one or more spat...
