A hash chain is a popular tool for improving the efficiency of several cryptographic applications. In spite of the computation efficiency of one-way function, the performance issue is a challenging research topic for chains with long length in resource-constrained environments. We propose a recursive algorithm of hash chain traversal for arbitrary length n with ⌈log2n⌉...
Recently, quality-of-service routing in dynamic, wireless multi-hop ad hoc networks becomes a hot research topic, and various QoS protocols are proposed. However, popular QoS routing protocols rarely provide multiple routes. Once links break due to node mobility, establishment of new routes leads to large control overhead and extra end-to-end delay. We design a quality-of-service routing protocol,...
For real-time traffic requirements in mobile ad hoc networks a novel and effective QoS admission control routing protocol (QACRP) is proposed in this paper. With a limit amount of extra overhead, QACRP can avoid network congestion by a simple and precise admission control to block most of overloading flow-requests in route discovery process. System simulations show that this proposed scheme can increase...
There has been an increasing demand for applications to support multicast communication in the mobile ad hoc networks. One of the primary concerns in the multicast communication is the feasible design of the multicast ad hoc routing protocols. Conventionally, the design of the multicast routing protocols can be categorized into the tree-based and the mesh-based schemes. These two types of protocols...
