New scheduling algorithm for wireless mesh networks

A new multi-rat scheduling algorithm for heterogeneous wireless networks

“…This fraction is required to be small. Fig.6illustrates the packet loss ratio of our proposed algorithm and the algorithm proposed in [9] when varying the number of users in the networks.…”

“…In [9], the authors propose a new algorithm for Wireless Mesh Networks (WMNs) that assigns priority to Voice over Internet Protocol (VoIP) traffic by taking into account four parameters: connection type, class of service, delay and channel quality. In this work, the quality of a link is determined by the SINR and the priority assigned to each packet is based on the earliest deadline.…”

“…In WMN, if node i is transmitting to node j, and E is the set of other nodes that transmit concurrently with i, then the SINR of link (i, j) is given by [9]:…”

“…Indeed, the algorithm calculates the logical arrival time l i,n when packet n arrives to the first router. The logical arrival time is determined based on the method explained in [9].…”

“…Based on [9], we propose the different modules of our proposed scheduling scheme: intersystem information, automatically and on demand [11].…”
