Multicast application is one of key value-add field to cellular mobile network. Most of researches focus on the whole system and ignore the structure inner cell. Current structure must let the signal strength satisfy the request of terminals located on the edge of cell, and this influence the capacity and data rate of multicast in same cell. we propose a cooperative relay multicast structure for cellular...
This paper proposes a novel Cross-layer Synchronous Dynamic Token Protocol (CLSDTP) in single channel that is based on token-passing scheme. The protocol introduces a token relay algorithm which is fast and adaptive to topology variation, presents a collision avoidance algorithm which solves the exposed and hidden terminal problem through the information of network topology and current data transmission...
Multicast application is one of key value-add field to cellular mobile network. Cooperative relay multicast network can be applied inside the cell of cellular system to improve performance of multicast sessions by adding relay nodes. This paper focuses on the optimization to relay nodes tree based on ant colony optimization (ACO). Besides cost and delay, power control is important to wireless relay...
