Since the emergence of ubiquitous computing, evaluating wireless network performances has become one of the major economic issues. Among the existing performance indicators, the network capacity, defined as the maximal amount of flow carried by a topology during a fixed time period, is essential. Some cross-layer characteristics have to be taken into account in order to optimally allocate the common...
Hybrid wireless-optical access network (WOAN) is a newly emerged network which integrates passive optical networks (PONs) and wireless mesh neworks(WMNs) to provide the ubiquitous, high bandwidth last mile Internet access. In WOAN, transmission delay for traffic up to the Internet consists of wireless path delay in WMNs and waiting delay at ONUs due to the TDMA schedule. The ONU from which transmission...
Interference ranges can dramatically affect the throughput in wireless sensor networks. While the transmission range defines the maximum physical range of a radio signal the interference range determines the area in which other nodes will be prevented from successful receiving or transmitting signals. In this paper we present an initial self organizing routing protocol for wireless sensor networks,...
