We propose two advancements in the existing Bloom filter based traceback schemes for WSNs (Wireless Sensor Networks): the support of directed queries, and a way of reducing the false positive rate at the nodes nearer to the sink. Simulation results show that the proposed mechanism can efficiently traceback the packets with very few false positives.
When the topology is mesh in ZigBee network, by changing the communication radius of the node, simulation result proves that the different effective communication distance of signal has a great influence on the network performance, meanwhile, the different values of key parameters MY_ROUTE_TIMEOUT and ACTIVE_ROUTE_TIMEOUT also cause some effect to the network performance. Through summarizing the simulation...
Recent technological advancements in the field of nanotechnology have increased the computation power of the wireless nodes while adhering to the energy constraints. This has made the use of the Wireless Sensor Networks (WSNs), more widespread, used in applications such as area monitoring, industrial monitoring, vehicle detection or military monitoring. Sensor nodes have made it possible to collect...
Recent trends in Wireless Sensor Networks (WSNs) have suggested converging to such being IPv6-based. To this effect, the Internet Engineering Task Force has chartered a Working Group to develop a routing protocol specification, enabling IPv6-based multi-hop Wireless Sensor Networks. This routing protocol, denoted RPL, has been under development for approximately a year, and this paper takes a critical...
Wireless Sensor Network (WSN) has become very important and are being used widely especially in embedded applications. Normally, these applications require numerous low cost, low power and low data nodes that communicating over multiple hop to cover a large geographical area. Introduction of 6LoWPAN makes it possible for IP address to be assigned on numerous sensor nodes and allow connectivity to...
