Bandwidth Allocation in Hexagonal Wireless Sensor Networks for Real-Time Communications

This paper presents an algorithm for bandwidth allocation for delay-sensitive traffic in multi-hop wireless sensor networks. The solution considers both periodic as well as a periodic real-time traffic in an unified manner. The authors also present a distributed MAC protocol that conforms to the bandwidth allocation and thus satisfies the latency requirements of realtime traffic. Additionally, the protocol provides best-effort service to non real-time traffic. They derive the utilization bounds of the MAC protocol.
