This poster-paper describes the current work which focuses on analyzing the multi-application requirements and capabilities of wireless sensor networks based on IEEE 802.15.4 and ZigBee standards. Keywords-component; multi-application wireless sensor networks

Transmission Control Protocol (TCP) is the dominant reliable transport protocol utilized in the Internet. Improving the performance of TCP associated with the presence of multi-hop is one of the research challenges in wireless mesh networks. Wireless mesh networks have large round trip time variations and these variations are dependent on the number of hops. In wireless mesh network, when conge...

Latest trend in research tend to fulfill requirements of the most talked about 5G networks. These networks need to be be engineered in terms of cost, energy and spectral efficiency, number of connected devices and latency. Cognitive Radio (CR) is one of the promising techniques to meet the above mentioned requirements that operates at microwave frequencies and exploits underutilized spectrum ba...

Multi-hop wireless networks are facing some research issues regarding routing protocols and security mechanisms. Multihop decentralized architecture, media access delay, lower link life, and multi-layer security threats are the key challenges which need to be address. The selection of optimal path for routing and the detection of multilayer security attacks cannot be achieved with the tradition...

Recent years have seen a proliferation in the use of wireless multi-hop networks in diverse scenarios ranging from community mesh networks to wireless sensor networks. As wireless networks find application in such wide-ranging arenas and are deployed at large scale, they will increasingly need to operate in the presence of heterogeneous, and often constrained, hardware capabilities. Furthermore...

In a wireless multi-hop network, one of the important challenges is how to route packets efficiently. The availability of many intermediate nodes between a source and a destination results in having many optional paths/routes to follow. The challenge is to pick an optimal path that satisfies the needed performance requirements-this is the responsibility of the routing protocol. There are four w...
