Abstract
A method and a system control admission for voice transmission over a multi-hop network. The method takes multiple parameters into account in order to make a decision and ensures that the system remains stable. The parameters may include options (e.g., aggregation level, bursting level, and transmission rate) and constraints (e.g., the number of users, access points, or sensing range of each user). The method computes the load of the network given each set of options and constraints and compares it against the packetization interval of the voice codec to check whether or not the system is stable. An algorithm of the method finds the best trade-offs between overhead reduction (e.g., due to contention and to packet headers) and a solution robust to channel errors, if links are noisy. If several stable solutions corresponding to different options exist, additional criteria (e.g., the least number of hops, the highest transmission rate) may be used to determine the final 'best' solution.
