A dynamic protocol stack (DPS) for ad hoc networks, together with a protocol stack construction scheme that is modeled as a multiconstrained knapsack problem is proposed. Compared to the traditional static protocol stack, DPS operates in a dynamic and adaptive manner and is scalable to network condition changes. In addition, a protocol construction algorithm is proposed to dynamically construct of...
The precondition of the whole known channel state information (CSI) is impractical in realistic system. To deal with this problem, a partial CSI based Affinity propagation Dynamic clustering algorithm was proposed in thispaper. In this algorithm, degree of wiliness to cooperate (DWC) was used to design the input matrix and a cooperation fact was introduced to adjust the number of clusters in clustering...
As Internet traffic grows explosively, high-speed switches and routers with large capability are becoming necessary, scalable multi-stage switching fabric is the next step. Nevertheless, current scheduling schemes based on random matching or round-robin dispatching for Memory-Space-Memory (MSM) Clos switching fabric, are subjected to the limited throughput and time delay under non-uniform traffic...
Emergency communication in heterogeneous networks with fragile connectivity is a challenging task. Emergency delay-tolerant network (EDTN) is a new network architecture based on the concept of delay tolerant networks (DTNs) to provide emergency service. However, existing transport protocols like TCP are not suitable to provide emergency service well with instable bandwidth and connectivity, because...
