The paper proposes a network coded cooperation protocol for the uplink transmission of relay assisted cellular networks characterized by non-ideal source - relay links. The proposed protocol employs Reed Solomon codes as network codes in order to improve the Block Error Rate (BLER) and Bit Error Rate (BER) performance over the slow varying fading channels. The paper presents also an algorithm for...
Adaptive network coded cooperation (ANCC) scheme has been shown to have better performance than the conventional repetition-based schemes and the space-time coded cooperation (STCC) frameworks for data transmissions from a large collection of terminals to a common destination in large wireless networks. However, the random selection strategy for ANCC protocol may generate many short cycles in the...
Cooperation diversity schemes employing space-time block coding (STBC) techniques have been proposed for wireless networks to increase systems capacity and coverage, by allowing multiple relay nodes distributed in space to assist the transmission between a given pair of terminals. Conventional relaying strategies, such as amplify-and-forward (A&F) and decode-and-forward (D&F), are designed...
In wireless networks, it is well-known that intermediate nodes can be used as cooperative relays to reduce the transmission energy required to reliably deliver a message to an intended destination. When the network is under a central authority, energy allocations and cooperative pairings can be assigned to optimize the overall energy efficiency of the network. In networks with autonomous selfish nodes,...
This paper analysis the performance of the ad-hoc network with a base station, a mobile and a third station acting as a relay. Three combining methods for the amplify-and-forward (af) protocol and the decode-and-forward (DF) protocol are compared. Simulations indicate that the amplify-and-forward (AF) protocol beats the decode-and-forward (DF) protocol under all these three combining methods. To combine...
