Big data set from sensors is often subject to corruption and losses due to wireless medium of communication and presence of hardware inaccuracies in the nodes. For a WSN application to deduce an appropriate result, it is necessary that the data received is clean, accurate, and loss-less. However, effective detection and cleaning of sensor big […]
E-STAR – SECURE AND RELIABLE ROUTING PROTOCOLS FOR HETEROGENEOUS MULTIHOP WIRELESS NETWORKS
ESTAR integrates payment and trust systems with the routing protocol with the goal of enhancing route reliability and stability. We propose a multidimensional trust system based on processing the payment receipts. ESTAR stimulates the nodes not only to relay others’ packets even if they have many credits, but also to stabilize the routes and report […]
DIDRIP – A NOVEL SECURE AND DISTRIBUTED DATA DISCOVERY AND DISSEMINATION IN WIRELESS SENSOR NETWORKS
This paper proposes the first secure and distributed data discovery and dissemination protocol named DiDrip. It allows the network owners to authorize multiple network users with different privileges to simultaneously and directly disseminate data items to the sensor nodes. Moreover, as demonstrated by our theoretical analysis, it addresses a number of possible security vulnerabilities that […]
A NOVEL SECURE AND DISTRIBUTED DATA DISCOVERY AND DISSEMINATION PROTOCOL IN WSN
The need of distributed data discovery and dissemination protocols is not completely new, but previous work did not address this need. We study the functional requirements of such protocols, and set their design objectives. Also, we identify the security vulnerabilities in previously proposed protocols. Based on the design objectives, we propose DiDrip. It is the […]
