In this paper, we propose a stochastic bursty-link model to simulate bursty behavior observed in wireless communications. Our stochastic bursty-link model works at the frame level where the probability of correctly receiving a frame is dependent on the results of previous transmissions. To accomplish this, our model uses a bursty probability adjustment(More)
In this paper, we revisit the problem of optimal tree-based routing structures for multicast in wireless multihop networks, but accounting for the impact of interference. Our analysis is based on the most accurate known interference model, namely the SINR-based physical interference model. We first study the problem in a low-intensity multicast scenario(More)
It is known that using a spatial TDMA (STDMA) access scheme can increase the capacity of a wireless network over CSMA/CD access scheme. Modern wireless devices are capable of transmitting at different data rates depending on the current network condition. However, little attention has been paid to how best is to use the multiple data rates capability. In(More)
In this paper, we consider the problem of building mesh-based multicast routing structures that account for the impact of interference in wireless multihop networks. Our analysis is based on the most accurate known interference model, namely the physical interference model. We first analyze interference-aware mesh structures that augment individual paths in(More)
Maintaining accurate neighbor information in wireless networks is an important operation upon which many higher layer protocols rely. However, this operation is not supported in the IEEE 802.11 MAC layer, forcing applications that need it to each include their own neighborhood mechanism, creating redundancies and inefficiencies and failing to capitalize on(More)
