Most previous work on real-time event-based communication has assumed infrastructure-based networks. The underlying assumption of this work is that application components are stationary and that a fixed network infrastructure exists to facilitate communication between them [1]. Ad hoc wireless networks comprise sets of mobile nodes connected by wireless links that form arbitrary wireless networ...

wireless sensor networks attracting a great deal of research interest. accurate localization of sensor nodes is a strong requirement in a wide area of applications. in recent years, several techniques have been proposed for localization in wireless sensor networks. in this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

In this paper we focus on the application of reinforcement learning to obstacle avoidance in dynamic Environments in wireless sensor networks. A distributed algorithm based on reinforcement learning is developed for sensor networks to guide mobile robot through the dynamic obstacles. The sensor network models the danger of the area under coverage as obstacles, and has the property of adoption o...

Wireless sensor networks have been widely used in many surveillance applications. Due to the importance of sensor nodes in such applications, certain level of protection need to be provided to them. In [1], Wang, Zhang and Liu first formally introduced the self protection problem in wireless sensor networks. A wireless sensor network is p-self-protected, if at any moment, for any wireless senso...

The wireless network is one of the most significant purposes behind the accomplishment of long range wireless communication. Frequent link failures are occurred in the sensor organised network due to obstruction, snags, message drop because of node energy depletion; Time to Live (TTL) lapsed and so forth. The total communication gets collapsed if there any lessening in the nature of corresponde...

Many scientists are convinced that the Modern Synthesis – the current paradigm in evolutionary biology – needs to be expanded within the framework of an Extended Evolutionary Synthesis (EES). A major task for the EES is to provide an explanation for the origins and extant features of biological complexity. Here we address this issue, focusing our investigation on genetic network architectures, ...

Wireless mesh networks are the next step in the evolution of wireless architecture, delivering wireless services for a large variety of applications in personal, local, campus, and metropolitan areas. Unlike WLANs, Mesh networks are self-configuring systems where each Access Point (AP) can relay messages on behalf of others, thus increasing the range and available bandwidth. Therefore, the key ...

Inherent freedom due to a lack of central authority of self-organised mobile ad hoc networks introduces challenges to security and trust management. In these kinds of scenarios, the nodes themselves are naturally responsible for their own security – or they could trust certain known nodes, called “micro-operators”. We propose an architecture for security management in self-organising mobile ad ...
