Mobile Sensor Deployment with Connectivity Guarantee

چکیده
In this paper, we consider the self-deployment of wireless sensor network. We present a deployment strategy for mobile wireless sensor network which maximizes the sensors covered area with the constraint that the resulting deployment provides a connected topology. Our deployment algorithm is distributed and is based on subset of neighbour for motion decision. Each node is considered as a particle and its movements are governed by the interaction with a part of its neighboring nodes. The interacting neighbors and the node’s direction are chosen based on the local relative neighborhood graph. Analytical and simulations results show that the resulting graph is connected, the distance between two sensors is maximized and thus the area covered is maximized. We also show by extensive simulation that some simple modifications of our algorithm allow different coverage schemes such as Point of Interest coverage and barrier coverage.

Nous présentons une stratégie de déploiement pour des capteurs mobiles qui maximise la surface couverte par chaque capteur avec comme contrainte que le réseau résultant soit connecté. Notre algorithme est distribué et le mouvement et la direction de chaque capteur se calcule en fonction d’un sous ensemble du voisinnage de ce capteur. Le sous ensemble de voisins que nous utilisons fait partie du sous graphe RNG. Une analyse et des simulations montrent que le graphe résultant est connecté, que la distance entre deux capteurs est maximisée et de ce fait, la surface couverte est aussi maximisée.

Representing a Model for Improving Connectivity and Power Dissipation in Wireless Networks Using Mobile Sensors
Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...
متن کاملPoints of Interest Coverage with Connectivity Constraints Using Wireless Mobile Sensors
The coverage of Points of Interest (PoI) is a classical requirement in mobile wireless sensor applications. Optimizing the sensors selfdeployment over a PoI while maintaining the connectivity between the sensors and the sink is thus a fundamental issue. This article addresses the problem of autonomous deployment of mobile sensors that need to cover a predefined PoI with a connectivity constrain...
