Cooperative communication becomes a popular area of research due to its strength and wide application scope in wireless networking and communications. This technique improves the communication performance largely in capacity enhancement, energy-efficiency, timeliness and contention. Power allocation plays an important role in the cooperative communication paradigm to get the desired performance...

Because of the gains like diversity, throughput, and the coverage extension provided by the multiple-input multipleout (MIMO) systems, it has been part of the various wireless communications standards. However, to reap the benefits offered by MIMO systems in size-constrained nodes, used in wireless communications, has been a challenging issue. To address this challenge, cooperative communicatio...

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 fountain codes at transport layer in the notion of cooperative relay communications to provide reliability and robustness for data transmission in wireless networks. Our basic id...

Cooperative communications can significantly enhance transmission reliability and bandwidth efficiency in wireless networks. However, the impact of cooperative communications on network-level upper layer issues, such as topology control, routing and network capacity, is largely ignored. At the same time, security is an important issue in MANETs and existing security schemes have significant imp...

Cooperative three-dimensional visualization and modeling applications allow a distributed group of users to work together with a model they share. To implement this kind of applications the underlying communications system must provide reliable and ordered multicast of users interactions. Due to the high complexity that characterizes the models, network bandwidth requirements have limited their...
