The quantity set LNCS 7439 and 7440 contains the complaints of the twelfth foreign convention on Algorithms and Architectures for Parallel Processing, ICA3PP 2012, in addition to a few workshop papers of the CDCN 2012 workshop which was once held together with this convention. The forty normal paper and 26 brief papers integrated in those court cases have been conscientiously reviewed and chosen from 156 submissions. The CDCN workshop attracted a complete of nineteen unique submissions, eight of that are integrated partly II of those court cases. The papers conceal many dimensions of parallel algorithms and architectures, encompassing basic theoretical techniques, functional experimental effects, and advertisement elements and systems.

To compute Δλi(l ) , i = 1, , N from (7), we need to obtain Δxi (λ ( l ) ) and ΔxJ i (λ (l ) ) , i = 1, , N first. To do so, we begin with rewriting the right-hand side of (5) into (8). -Y. -C. , N ( ) 1  min ΔxiT  ∇ 2 f i ( xi ( k ) ) + η I  Δxi + ∇f i xi ( k ) 2  Δxi T Δxi + λiT gi ( xi ( k ) , xJi (k ) ) (9) + λiT ∇ x giT ( xi ( k ) , xJi ( k ) )Δxi  +  λ j ∇ x g jT ( x j (k ) , xJ j ( k ) )Δxi   i j∈Ji i Notably, subproblem i shown in (9) to be solved in processor i is an unconstrained optimization problem with quadratic objective function, which can be solved analytically.

3 Proposed Parallel Algorithm To exploit the computing power of the processor network using parallel computation, we need to decompose the coupling nonlinear network optimization problem (1). In general, the dual method can achieve the decomposition effect [10]. However, as mentioned above, the objective function and the equality constraints of (1) are nonlinear, which implies that (1) is a non-convex optimization problem. Therefore, there will be a duality gap between the optimal objective values of the primal and the dual problems [10].

End while Now we are focusing on the contributions to our controllable resiliency of WSN. Following the definition of resiliency is the ability of a network to continue to operate in presence of k compromised nodes [21] we assume the threshold for the targeted WSN is 30% of the total nodes became compromised nodes.
