We investigated what effect contention had on the flow capacity of Demand Wakeup MAC (DW-MAC), which is a state-of-the-art multi-hop MAC protocol.
The flow from a source node to the sink is affected by contention because of the sharing characteristic of wireless channels. We investigated what effect ...

The performance evaluation results show that the energy consumption of a relay node reduced by 11.4 -- 64.8%. The overall throughput of the network increased by ...
This paper focuses on a more fundamental form of unfairness that arises due to unequal contention opportunities at a node.
The coupling of the problems and the grasping properties of TCP could lead to instability which results in a decrease of throughput and excessive long delays in ...

In the heavy traffic case, queuing delay becomes a dominant factor. The above delays are inherent to a multi-hop network using contention-based MAC protocols.
For security reasons, the MAC protocol should prevent overhearing; moreover as the network topology may be unknown we are looking for a distributed protocol.
