In this paper we investigate the ratio of dwelling time in control channel (CCH) and service channel (SCH) for single channel devices deploying WAVE (Wireless Access in Vehicular Environments) protocols. Based on analytical model for both channels and four traffic types we present tradeoffs in channel performance when CCH/SCH duty cycle is changing. Our results show that, when video traffic is absent,...
Efficient operation of a cognitive personal area network (CPAN) may be achieved if each data transmission is taxed by requiring the transmitting node to participate in cooperative sensing for a prescribed time period. We investigate the data transmission performance of this approach as well as its sensing accuracy. Through adaptive management of both the sensing process and data transmission, we show...
Mapping and dynamic routing in a wireless network are essential and basic operations that are the prerequisites for all higher order interactions between nodes on that network. The Intent of network mapping by multi mobile software agents is to obtain the topology of network in a distributed manner. In this paper we examine how software agents can wander in an unknown Ad hoc network with cooperation...
Performance of cognitive personal area networks is critically dependent on the accuracy of channel sensing. To ensure smooth operation of a cognitive PAN, all nodes that have data to transmit must take part in the sensing process. However, sensing affects transmission and vice versa, and a balance between sensing and data transmission must be found. One mechanism suitable for achieving this balance...
