This paper proposes a cross-layer wireless routing protocol called REAR (Radio Environment Adaptive Routing Protocol), which operates with Cognitive Radio (CR) Mobile Ad Hoc Networks (CRMANET). Unlike conventional on-demand routing protocols for ad hoc networks, the design of REAR allows nodes along the route to adjust the next hop according to real-time radio environment conditions during the transmission...
Development of services that span over the Internet and telecom networks is driving significant efforts towards the integrated of services offered by telecom operators. In this paper, we design and implementation of enhance state machine for telecom Web service considering the specific characteristics state, asynchronous, events driven communications in telecom domain. We focus on the design and implementation...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
