Real-time multimedia applications are time sensitive and require extra resources from the network, e.g. large bandwidth and big memory. However, wireless sensor networks (WSNs) suffer from limited resources such as computational, storage, and bandwidth capabilities. Therefore, sending real-time multimedia applications over WSNs can be very challenging. For this reason, we propose an adaptive multi-flows...
The flooding zone initialization protocol (FZIP) was proposed as a mechanism to provide power efficient flooding for real-time multimedia data over wireless sensor networks (WSNs). FZIP can initialize different FZ sizes with different performance levels (i.e. loss rate, latency, and overhead). Increasing the FZ size increases redundancy which in turn reduces packet loss but consumes extra power overhead...
Flooding protocols have shown to be failure resilient and robust in transporting data over multi-hop wireless networks, e.g. wireless sensor networks and ad hoc networks. However, flooding protocols are considered to be less efficient in power consumption compared to unicast based protocols. In this paper, we present our Flooding Zone Initialization Protocol (FZIP) which constrains the flooding storm...
This paper examines the problem of grouping wireless sensor nodes forming a network into a set of spatial clusters. The technique for grouping the nodes proposed here, exploits the spatial degradation in wireless signals to group the nodes into regions based on the packet loss rate. The technique is validated on datasets obtained from actual wireless sensor networks. The obtained results support the...
