CSMA/CN: carrier sense multiple access with collision notification
A wireless transmitter learns of a packet loss, infers collision, only after completing the entire transmission. If the transmitter could detect the collision early (such as with ...

Increasing Sensor Network Lifetime by Identifying and Leveraging Nodes with Excess Energy In Heterogeneous Networks
We propose and evaluate wireless sensor routing algorithms designed to extend the lifetime of a heterogeneous wireless sensor network. The network is heterogeneous in the sensorsâ...

A coordinate-based approach for exploiting temporal-spatial diversity in wireless mesh networks
In this paper, we consider the problem of mitigating interference and improving network capacity in wireless mesh networks from the angle of temporal-spatial diversity. In a nutsh...

A simple Cooperative diversity method based on network path selection
Cooperative diversity has been recently proposed as a way to form virtual antenna arrays that provide dramatic gains in slow fading wireless environments. However, most of the prop...
