An enhanced HCF for IEEE 802.11e wireless networks
In this paper the behavior of the upcoming MAC protocol for wireless LANs IEEE 802.11e is investigated. Based on the results, we propose an enhancement for Hybrid Coordination Fun...

PARMA: A PHY/MAC Aware Routing Metric for Ad-Hoc Wireless Networks with Multi-Rate Radios
Ad-hoc wireless networks with multi-rate radios (such as 802.11a, b, g) require a new class of MAC/PHY aware metrics that take into account factors such as physical-layer link spe...

Diversify sensor nodes to improve resilience against node compromise
A great challenge in securing sensor networks is that sensor nodes can be physically compromised. Once a node is compromised, attackers can retrieve secret information (e.g. keys)...

Exploiting Rate Diversity for Multicasting in Multi-Radio Wireless Mesh Networks
: A multi-rate capable IEEE 802.11a/b/g node can utilize different link-layer transmission rates. Interestingly, multi-rate capability is defined by IEEE 802.11 standards only for...
