Performance evaluation of a new multiaccess protocol for local area networks
A new self-adaptive protocol for broadcast networks, capable of operating efficiently under bursty traffic conditions and allowing stations to transmit packets of variable length, is introduced. Fixed-assignment protocols such as TDMA have known drawbacks, which are resolved by learning protocols such as LTDMA. However, the fact that LTDMA uses fixed-sized timeslots can result in network equipment overloading as well as wasted timeslots and reduced channel usage. The proposed Variable Packet Length/LTDMA protocol is tested by using real LAN traffic traces and it is proved that it successfully resolves the above issues and achieves a high throughput-delay performance when operating under realistic traffic conditions.
