In this chapter we propose the one4all cooperative access strategy to introduce a more efficient uplink access strategy for cellular networks. The one4all scheme is based on the cellular controlled peer-to-peer network architecture. The basic idea is that mobile devices form a cooperative cluster using their short-range air interface and one device contends the channel for itself and all neighboring devices within the cluster. This strategy reduces the number of mobile devices involved in the collision process for the wireless medium resulting in larger throughput, smaller access delay, and less energy consumption. Based on an analytical model, the proposed strategy is compared with the two existing strategies RTS/CTS (request to send/clear to send) and packet aggregation. The results show that the proposed cooperative scheme has better throughput performance than packet aggregation and has much higher throughput than the conventional RTS/CTS scheme. Furthermore, the newly introduced scheme outperforms packet aggregation in terms of channel access delay and energy consumption.
