Service function chain embedding algorithm with wireless multicast in mobile edge computing network by Kan WANG, Nan ZHAO, Junhuai LI, Huaijun WANG

“…To resolve the excessive system overhead and serious traffic congestion in user-oriented service function chain (SFC) embedding in mobile edge computing (MEC) networks,a content-oriented joint wireless multicast and SFC embedding algorithm was proposed for the multi-base station and multi-user edge networks with MEC servers.By involving four kinds of system overhead,including service flow,server function sustaining power,server function service power and wireless transmission power,an optimization model was proposed to jointly design SFC embedding with multicast beamforming.Firstly,with Lagrangian dual decomposition,the problem was decoupled into two independent subproblems,namely,SFC embedding and multicast beamforming.Secondly,with the L<sub>p</sub> norm penalty term-based successive convex approximation algorithm,the integer programming-based SFC embedding problem was relaxed to an equivalent linear programming one.Finally,the non-convex beamforming optimization problem was transformed into a series of convex ones via the path following technique.Simulation results revealed that the proposed algorithm has good convergence,and is superior to both the optimal SFC embedding with unicasting and random SFC embedding with multicasting in terms of system overhead.…”

False data filtering algorithm without relying on MAC authentication for wireless sensor networks by YI Ye-qing1, LIN Ya-ping1, PENG Ge1, ZHOU Si-wang2, YANG Si-qing1

“…A multiple semi-fragile watermarks algorithms was proposed,considering the characteristics of clustering col-laboration aggregation in WSN.The generation of watermarks,embeding and extraction were completed by not a single node,but a fixed number of witnesses nodes which selected within the same clusters.This algorithm could against leak-age of keys when a single node was captured,and it could save energy costs also.On this basis,a false data filtering al-gorithm was proposed based on multiple semi-fragile watermarks,this algorithm could authenticate the accuracy,com-pleteness and fresh using watermarks embedded in data,without relying on MAC authentication.It provided a compari-son between the scheme and previously proposed schemes.The analysis and simulation results indicate significant im-provement in probability of filtering false data,energy saving and having robust,yet fragile characteristics,which support lossy in-network data processing and resist of the noise in certain.…”
