Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate ...
The ns-2 simulator has limited support for simulating 802.11based wireless mesh networks. We have added the following new features at the MAC and PHY layer of ns-2: (i) cumulative...
: Next to authentication, secure key exchange is considered the most critical and complex issue regarding ad-hoc network security. We present a low-cost, (i.e. low hardware-complex...
— Hydra is a flexible wireless network testbed being developed at UT Austin. Our focus is networks that support multiple wireless hops and where the network, especially the MAC,...
