The evolution of mobile multimedia services outlines a trend towards the coexistence of wireless overlay networks. These networks have overlaid coverage areas and are composed of a hierarchical structure ranging from in-room to in-building, campus, metropolitan, and wide-areas. For these networks to work as a seamless inter-working, optimal mobility(More)
Trilateration is a common operation to find the object location using its distances or range measurements to three other known points or stations. Traditionally, this problem has been solved either by algebraic or numerical methods. These methods involve long and complex geometric computations which are usually implemented in software. An approach that(More)
In this paper, we developed an analytical model of a time-threshold based bandwidth allocation scheme for voice calls in cellular networks. The main idea in this scheme is based on monitoring the elapsed real time of handoff calls and according to a time-threshold parameter; a handoff call is either prioritized or treated as a new call. The scheme is(More)
In this paper, a time-threshold based multi-guard bandwidth allocation scheme for voice calls is presented. The main idea of the new scheme is based on monitoring the elapsed real time of handoff calls and according to a time threshold (t<sub>e</sub>), a handoff call is either slightly-prioritized or fully-prioritised. A slightly-prioritized handoff call(More)
