The COMPASS Multihop Framework for TinyOS
نویسنده
چکیده
TinyOS 2.x supplies a well-designed single hop messaging layer for applications, but there is no standardized multihop framework. To address this issue, we surveyed a large number of applications [1] to determine the addressing techniques and messaging stack features used in sensor networks. From the results of this survey, we designed a multihop networking API [2] to address the needs of application designers at the messaging layer in a unified way. This framework [3] intends to implement that API. The key goals of this include: • Multihop routing with several addressing modes based on: – Node address (single node, multiple nodes, or a list of nodes) – Geographical region – Device hierarchy • Intercept messages to be forwarded • Control transmission effort • Congestion management • Support self-organized device hierarchies

Design and Implementation of TARF : A Trust – Aware Routing Framework WSN ’ s
The multihop routing in wireless sensor networks (WSNs) offers little protection against identity deception through replaying routing information. An adversary can exploit this defect to launch various harmful or even devastating attacks against the routing protocols, including sinkhole attacks, wormhole attacks, and Sybil attacks. The situation is further aggravated by mobile and harsh network...

In wireless sensor networks (WSNs), asynchronous sleep wake scheduling protocols can significantly reduce energy consumption without incurring the communication overhead. However, the savings could come at a significant cost in delay performance. In this paper, we consider anycast-based integrated routing framework (AIRF) to reduce the cost in delay performance of communications in multihop WSN...

متن کاملA Remote Code Update Mechanism for Wireless Sensor Networks
Wireless sensor networks consist of collections of small, low-power nodes that interface or interact with the physical environment. The ability to add new functionality or perform software maintenance without having to physically reach each individual node is already an essential service, even at the limited scale at which current sensor networks are deployed. TinyOS supports single-hop over-th...
