Most Mobile Ad hoc Networks (MANETs) research is based on a single channel. Nonetheless, multi-channel is an approach that can increase network capacity by transmitting traffic on different channels in an interference area. Channel assignment and channel switching, however, are two main challenges when the common communication channel is no longer available using the multi-channel scheme. We pr...

Campus and enterprise wireless networks are increasingly characterized by ubiquitous coverage and high traffic demands. An efficient channel assignment of access points (APs) in these networks has the potential to greatly improve wireless LAN performance. Therefore, previous studies have investigated methods for determining effective channel assignments. Existing approaches, however, do not ada...

Traditionally, the coordination of multiple traffic signals and the traffic assignment problem in an urban street network are considered as two separate optimization problems. However, it is easy to see that the traffic assignment has an influence on the optimal signal coordination and, vice versa, a change in the signal coordination changes the optimal traffic assignment. In this paper we pres...

How to model traveler’s perception of travel time is always an important issue in the development of traffic assignment models. Since travelers rarely have perfect knowledge of the road network or of the traveling conditions, they choose routes based on their perceived travel times. Traditionally, travelers’ perceived travel times are treated as random variables, leading to the stochastic traff...

This paper proposes a distributed and adaptive channel assignment (D-CAS) scheme for wireless sensor networks. D-CAS performs statistical analysis of load pattern of the individual cluster and adjusts channel assignment dynamically as per requirement generated by the current cluster’ traffic load. It follows a static schedule during infrastructure establishment based on initial traffic conditio...
