The Problems of Control in Wireless Sensor and Mobile Ad-Hoc Networks

Abstract

One the main problem during development of self-organized networks such as wireless sensor (WSN) and mobile ad-hoc networks (MANET) is creation of effective control system, which can cover a lot of management tasks such as topology management, routing management, radio resource management, security management, quality of service management etc. For this purpose it proposed hierarchical model of intelligent control system for WSN and MANET described in Sect. 1. The novelty of the model lies in using the graph theory to make a formal description of the functional subsystems of the network (vertices of the graph) and their interaction processes (edges of the graph). Using of proposed model can accelerate and systemize the network design process considering their functioning environment and hierarchical structure of their control system. Using of intellectual agents technology and multiagent systems allows to minimize the service traffic and use network and node resources more efficiently. One particular management task intended to plan the optimal topology of network nodes is described in Sect. 2. There was formulated a mathematical statement of the problem of finding a rational WSN topology using unmanned aerial vehicles (UAVs), which consists of problem of sensor localization in monitoring zone and problem of UAV relays localization in the space for the organization of connected network with desired characteristics. Rational WSN topology, built according to these principles, will reduce traffic and reduce energy consumption at the nodes, which in turn will increase network lifetime and reduce the total cost of its maintenance.
