Coordinated Hybrid Automatic Repeat Request; Extended Version
We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is allocated to other users, to improve the network outage probability and the users’ fairness. The results, which are obtained for singleand multiple-antenna setups, demonstrate the efficiency of the proposed approach ...
متن کاملFormal verification of a Cooperative Automatic Repeat reQuest MAC protocol
Cooperative communications, in which a relay node assists the source node to deliver its packets to the destination node thus adding diversity, is gaining more attention within the research community. The initial studies on the physical layer have shown significant gains from cooperative diversity in terms of reliability, coverage range and energy efficiency. A Cooperative Automatic Repeat reQu...
متن کاملDetection of Malicious nodes using Selective Repeat Automatic Repeat Request protocol for Wireless Sensor Networks
Malicious nodes in wireless sensor network cause serious effects on critical factors like network lifetime, energy consumption and congestion control causing delay in delivery of messages. A lot of methods are being used to detect malicious nodes. In this paper we try to overcome the limitations of existing Watchdog method. For this we propose the method of detection of malicious nodes using se...

متن کاملRecent advances in cooperative communications for wireless systems
Cooperative transmission techniques have been proposed in order to improve the system performance in terms of availability, coverage range and throughput. The cooperative techniques and the smart interactions among the network nodes have been proposed in order to enhance the QoS of their connections and the performance of thewhole network. Radio channel and physical communication characteristic...
