Different Sensing Coverage Degrees In3d Mobile Sensor Actor Networks

چکیده
Given a 3D space where should be supervised and a group of mobile sensor actor nodes with limited sensing and communicating capabilities, this paper aims at proposing a distributed self-deployment algorithm for agents to cover the space as much as possible by considering non-uniform sensing coverage degree constraint of environment while preserving connectivity. The problem is formulated as coverage maximization subject to connectivity and sensing coverage degree constraint. Considering a desired distance between neighbouring nodes, an error function which depends on pairwise distance between nodes is described. The maximization is encoded to an error minimization problem that is solved using gradient descent algorithm and will yield in moving sensors into appropriate positions. Simulation results are presented in two different conditions that importance of sensing coverage degree support of environment is very high and is low.

متن کاملRecharging Sensor Nodes Using Implicit Actor Coordination in Wireless Sensor Actor Networks
Wireless sensor actor networks are composed of sensor and actor nodes wherein sensor nodes outnumber resource-rich actor nodes. Sensor nodes gather information and send them to a central node (sink) and/or to actors for proper actions. The short lifetime of energy-constrained sensor nodes can endanger the proper operation of the whole network when they run out of power and partition the network...
