Tutorial-1: Cooperative Communications for Wireless Sensor and Next Generation Networks
Duration: 3 Hours
High capacity aspect in future generation wireless systems is targeting a lot of attention because of the constantly growing demands for information in a ubiquitous manner. However, the data rate capability of the wireless networks is limited by channel fading and other transmission impairments. In order to combat channel fading, an efficient technique is to exploit the spatial diversity by having multiple radios transmit the same message signal. The technique, known as distributed multiple-input multiple-output (MIMO) was proposed as compared to the co-located MIMO, where the main difference is that the multiple antennas at the front-end of the transmitters are distributed among spatially separated radio nodes. Therefore, multiple nodes create a virtual antenna array acquiring higher diversity gains. This style of cooperative communication/transmission (CT) is becoming popular in the past several years in both the sensor and the cellular networks. Cooperative communications has emerged as a leading candidate transmission protocol especially in wireless sensor network (WSNs) where a large number of sensor nodes are deployed to gain advantages such as improved sensing, structural health monitoring, body area networks. This boom has nowadays resulted in the context of machine-to-machine (M2M) networks for future 5G systems. However, cooperative communications in single or multi-hop networks have severe challenges to be operable. This tutorial will provide an in-depth review of various techniques, which have been devised for such networks in the presence of wireless channel impairments. The tutorial will start from the basics of cooperative communications, how relays work, the role of wireless channel in a very simple dual hop network. The tutorial then proceeds to include cooperative multi-hop networks and their mathematical and stochastic modeling in details. The state-of-the-art will be discussed at the end with open challenges and research prospects to this area.Key objectives
