Wireless sensor networks (WSNs) heavily rely on a dense deployment of sensor nodes in order to ease deployment, increase fault-tolerance and network coverage, so that events do not go undetected. A dense deployment however results in several sensor nodes close to each other detecting and transmitting event reports at almost the same time, resulting in severe contention for channel access. Chann...
A Dynamic MAC protocol is developed for WCDMA wireless multimedia networks. It uses multiple slots per frame allowing multiple users to transmit simultaneously using their own CDMA codes. The proposed MAC protocol is based on contention .If there is low contention users can access any slots and if there is high level contention the owners of the slots have priority to access slots .If the owner...
Contention based bandwidth request mechanism is suggested for best effort services in WiMAX networks. The design of contention mechanism depends on the error model that reflects the transmission failure. In this paper, we have developed an error model by integrating the collisions due to contention, unavailability of bandwidth and channel error. The conventional exponential increase and exponen...
In this inductive theory building paper, I examine the impact of social media on a social phenomenon. I particularly focus on a social phenomenon that concerns firms—the entrainment of contention to innovation. The entrainment of contention to innovation is defined as the alignment of the pace and/or timing of contention (e.g., opposition, petition, protest) with those of firms’ innovation. To ...
Transactional memory (TM) contention management (CM) is the process of handling memory conflicts in transactions. Contention managers were first proposed as a way of separating transactional progress from correctness and to prevent transactional starvation. While significant work in the area of contention management has been done, most prior work has focused on preventing starvation through var...
The irregular switch-based network of workstations is fast becoming a cost-eeective platform for high performance computing. This paper presents eecient multicasting with reduced link contention on irregular networks with switch-based cut-through interconnection and unicast message passing. First, it is proved that for an arbitrary irregular network with a typical deadlock-free, adaptive routin...
