IEEE 802.15.4, a MAC/PHY protocol for low power and low data rate wireless networks, is emerging as the popular choice for various monitoring and control applications. Depending on the application, the traffic load on an IEEE 802.15.4 network may vary over a wide range. The performance of the protocol, measured in terms of the packet loss probability and the packet latency, depends upon the prevailing...
In this paper, we describe our modifications to ospfd, a popular open-source implementation of OSPF routing protocol. The ospfd software can also be run in simulation mode, where processes, representing individual routers, communicate with each other over UDP sockets. Even though ospfd provides a fine-granularity implementation of OSPF protocol, its simulation mode operation leaves a lot to be desired...
Wireless communication among sensor devices, enabled by IEEE 802.15.4 protocol, is increasingly replacing the existing wired technology in a wide range of monitoring and control applications. IEEE 802.15.4 networks typically operate in 2.4 GHz ISM band, which is used by popular IEEE 802.11 (WiFi) networks as well. An overlap between the channels used by IEEE802.15.4 and IEEE 802.11 networks may adversely...
