A Distributed Clustering Algorithm (DCA) and a Mobility-Adaptive (DMAC) algorithm are presented that partition the nodes of fully mobile network: (ad hoc network) into clusters, this giving network hierarchical organization. Nodes grouped by following new weight-based criterion allows choice coordinate clustering process based on node mobility-rebated parameters. The DCA is suitable for "quasistatic" ad networks. It easy to implement its time complexity proven be bounded parameter depends...

RF energy harvesting (RFH) is emerging as a potential method for the proactive replenishment of next generation wireless networks. Unlike other techniques that depend on environment, RFH can be predictable or demand, and such it better suited supporting quality-of-service-based applications. However, efficiency scarce due to low RF-to-DC conversion receiver sensitivity. In this article, we identify novel communication enable enhance usefulness RFH. Backed by some experimental observations...

We consider the problem of securing communication in large ad hoc networks, i.e., wireless networks with no fixed, wired infrastructure and multi-hop routes. Such e.g., sensors, are deployed for applications such as microsensing, monitoring control, extending peer-to-peer capability smaller group network users. Because nodes these which we term pebbles their very limited size number, resource constrained, only symmetric key cryptography is feasible. propose a management scheme to...
