This paper focuses on fault tolerance of super-nodes in P2P-SIP systems. The large-scale environments such as P2P-SIP networks are characterized by high volatility (i.e. a high frequency of failures of super-nodes). Most fault-tolerant proposed solutions are only for physical defects. They do not take into account the timing faults that are very important(More)
Almost all WSNs (Wireless Sensor Networks) are deployed with some redundancy degree and redundancy is used only for robustness objectives. If not handled in an intelligent way, redundancy results in energy wasting because of (often unnecessary) redundant transmission and reception operations. We propose to take benefit from measurement redundancy to(More)
