This paper proposes a technique for topology control (TC) of wireless nodes to meet Quality of Service (QoS) requirements between source and destination node pairs. The nodes are assumed to use a TDMA (Time Division Multiple Access) based MAC (Medium Access Control) layer. Given a set of QoS requirements, a set of wireless nodes and their initial positions, the goal is to find a topology of the nodes...
An essential part of the provision of quality of service (QoS) is the reservation of bandwidth which is a scarce resource in a mobile ad hoc network. In this paper, we describe how to enhance the guarantees for bandwidth reservation in a Time Division Multiple Access (TDMA) based ad hoc network where the bandwidth is expressed in terms of the number of time slots. We devise a scheme for determining...
Bandwidth resource allocation and scheduling has posed a challenging problem in wireless sensor networks. This paper provides a survey on the current state-of-the-art researches in this important area. Bandwidth reservation is considered in terms of time slot allocation in a pure TDMA or TDMA/CSMA based networks. We first overview different approaches for time slot allocation in a star network topology,...
