“…The ALLow Improved Access in the Network via Cooperation and Energy Savings (ALLIANCES) scheme, developed in [7] and [8], achieves cooperative diversity in spatial and temporal domains and, as a result, it properly functions even in a slowly time-varying channel environment. In this scheme, collided packets are buffered and at least one cooperative transmission epoch (CTE) is triggered once collisions occur.…”

“…The main contributions of this paper are summarized as follows. First, different from the existing techniques [7]- [9], we utilize all the information collected both in the collision slot and CTE slot(s) to jointly retrieve data packets at the final CTE slot. The cooperative diversity can thus be fully achieved.…”

Abstract-Cooperative transmission among wireless network nodes can be exploited to resolve collisions and thereby enhance the network throughput. Incorporation of multi-beam adaptive array (MBAA) at a base station/access point (destination) receiver has been shown to improve the network performance. In this paper, we propose an efficient cooperative wireless medium access scheme that exploits novel relay selection methods in a network equipped with MBAA at the destination receiver. Unlike existing techniques that require the estimation of angles-of-arrival (AoAs), the proposed scheme uses the spatial correlation among users for simpler but more effective collision detection and resolution. We present two useful relay selection methods based on channel gain and spatial correlation. It is shown that the joint use of an effective relay selection method and an MBAA in a wireless network can significantly improve the uplink throughput. The throughput of the proposed scheme and its upper bound are analytically derived. Numerical and simulation results have demonstrated significant performance enhancement achieved by the proposed cooperative wireless medium access scheme.

“…Laneman et al [9] and others [2,6] have developed a set of cooperative communication scheme for distributed wireless network like: ad hoc networks or sensors networks.Theirs respective works has paved the way for a lot of studies using cooperative transmission on a real Mac layer framework. Ji et al [8] and Lin et al [10] proposed different framework for Cooperative MAC protocol. These solutions are based on network-assisted diversity multiple access (NDMA).…”

Abstract-This article proposes a new Mac layer scheme (WSC-MAC) for Wireless Sensor Network (WSN) improving the overall the network reliability by using cooperative communication. We focus our work on a way to define a relay node among the neighborhood of a node, efficiently and with only few signaling messages. We developed a solution based on an automatic forwarder selection and a link state evaluation in order to define the relay node. This automatic selection uses a group identifier uniformly spread in the network and ensures that only few nodes at the time will be chosen as relay. As the sensor nodes switch from active mode to sleep mode, we based our solution on the Long Preamble Emulation (LPE) Mac layer Algorithm which emulates the asynchronous MAC protocol proposed in [13]. Our Simulations results show that WSC-MAC increases the overall reliability of the sensor network and adjusts to large variety of node density.

“…However, all these methods just only get the better throughput through the different retransmission schemes. For example, Rui Lin proposed a new wireless network medium access protocol based on the cooperation in [2].Dr. WeiJi presented a novel medium access scheme to deal the unfairness selection of the relay [3].…”

Abstract-This paper proposed a retransmission scheme based on the blind separation method, named independent component analysis(ICA),to resolve the collision problem in random access wireless network and a new method to devise the Identification(ID)sequences which can resolve the problems of ICA and help to reduce the length of ID sequences. The proposed method can work effectively under the fast-varying and slow-varying channels from the simulation results.
