A wireless sensor network (WSN) consists of sensor nodes which can self-organize to form a wireless network with the purpose of relaying information such as measurements to a base station. Sensor nodes are normally with limited power supply, processing and transmission capability. Some existing WSN designs require complex routing protocols, and others are(More)
Path protection employs a link-disjoint secondary backup path to protect the primary path to ensure continuity of network services. Nevertheless, existing path protection schemes are either less efficient in resource utilization, such as that in dedicated path protection (eg., 1+1 protection) or cannot respond to link failure quickly enough for real-time(More)
A challenging issue for network communication is to provide uninterrupted network services even when a link failure occurs. Path protection offers a promising solution by employing a link-disjoint secondary backup path to protect the primary path. Existing path protection mechanisms can be classified into 1+1 protection, 1:1 protection 1:N protection and(More)
