Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

Optimal Power Management to Minimize SER in Amplify and-Forward Relay Networks

This paper studies optimal power allocation to minimize symbol error rate (SER) of amplify-and-forward cooperative diversity networks. First, we analytically solve optimal power allocation problem to minimize SER for three different scenarios, namely, multi-branch single-relay, single-branch multi-relay and multi-branch multi-relay cooperative diversity networks, all subject to a given total re...

The Throughput for Multi-hop Relay Wireless Sensor Networks Based on Cooperative Diversity

This paper studied the problem of the throughput of multi-hop multi-relay wireless sensor networks based on the cooperative diversity technology. At first, the paper established the cooperative diversity model for multi-source, multi-sink and multi-relay sensor networks, on which the specific expression of throughput of wireless sensor networks was deduced, it not only prove that the throughput...

A cross-layer multi-hop cooperative network architecture for wireless ad hoc networks

In this paper, a novel decentralized cross-layer multi-hop cooperative network architecture is presented. Our architecture involves the design of a simple yet efficient cooperative flooding scheme, two decentralized opportunistic cooperative forwarding mechanisms as well as the design of Routing Enabled Cooperative Medium Access Control (RECOMAC) protocol that spans and incorporates the physica...
