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...
This paper proposes a novel Spatial-multiplexing Time Division Dynamic Token Protocol (STDTP) in single channel that is based on token-passing scheme with the incorporation of TDMA and spatial-multiplexing. 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...
Multicast applications are regarded as one of the key value-added fields. We propose the relay nodes structure to enhance the capacity and quality of multicast inside the cell. This paper focuses on the general structure design for relay network inside cell based on multimedia multicast broadcast services (MBMS) of 3GPP. First, we propose our relay network scheme inside cell. And then, we analyze...
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...
