Providing efficient and reliable data transport is a challenging problem for a variety of emerging applications which require reliable data packet delivery in wireless networks. In this paper, we propose to incorporate erasure codes at transport layer in the notion of cooperative relay communications to provide reliability and robustness for data transport in wireless networks. Our basic idea is to...
Providing reliable multicast (RM) service in Ad Hoc networks is very challenging due to the significant packet losses. To improve the reliability, data packets can be cached at designated nodes for future possible retransmission in loss recovery. How to cache packets to optimize the performance of loss recovery is an important issue in RM protocol and this problem has not been well investigated. In...
To reduce influence of node failure and achieve high reliability in communications, research on node protection algorithm is needed. In this paper, we first provide an overview of current research of redundant tree algorithm (RT). Then we propose a new algorithm called single node protection algorithm (SNP) based on previous redundant tree algorithm, which is used to achieve recovery form single node...
The integration of Wireless mesh networks (WMNs) with other networks (e.g. Internet, cellular, IEEE 802.11, sensor networks, etc.) requires an effective and robust congestion control algorithm to maintain network stability and achieve a high network resource utilization. In this paper, we address the problem of congestion control for WMNs with multi-channel MAC. We formulate the design of congestion...
