This paper proposes a novel area-efficient folded modified convolutional interleaving (FMCI) architecture for MAP decoder. The end to end delay of proposed FMCI requires only 2M. In addition, the number of latches can reduce to M-2. Hence the proposed FMCI architecture has lesser end to end delay and minimizes the number of latches usage as compare with block interleaving and convolutional interleaving. In addition to this the life time analysis and forward-backward allocation has also been implemented. Therefore, FMCI architecture can reduce the memory elements about 88% as compare with block interleaving for the particular condition when M = NJ

Sheltered communication is a precise significant concern in any kind of network. This research focuses on secure and reliable wireless message arrangement. Through relating trust based and cryptography based approach we can progress wireless communication security and reliability effectually of Advanced Metering Infrastructure. Wireless Sensor Network used as a communiqué arrangement for AMI.Nodes(Sensors) are employed intended for a Home Area Network around 10-60.The performance of security and reliability calculated through energy depletion, delay, packet transfer ratio or packet delivery ratio (PDR),throughput and overhead of the sensor nodes. Diverse categories of attacks arises on wireless communication infrastructure. This research deliberated Denial of Service (DoS) type attack. Through linking Elliptic Curve Cryptography (ECC) for secure routing and authenticated anonymous secure routing (AASR) for reliable route routing tries to improve reliability and security of wireless communication infrastructure of AMI using NS2(Network Simulator2) simulation platform. Operative routing delivers radical change in enactment of wireless communication infrastructure. Proposed AASR protocol and ECC protocol admirably delivers virtuous results compared to surviving protocols.

A routing and wavelength assignment (RWA) technique for supporting multipath traffic in optical wavelength-division multiplexing (WDM) mesh network is proposed in this paper. The network can be preceded by accomplishing two processes: one is establishing connection node and the second one is identifying the multipath and assigning wavelength. The connection node is selected based on the load and current traffic-carrying capacity of that node. During wavelength allocation mechanism, cost function is considered as the major criterion. Based on the cost involved in every path, the wavelengths are selected such that wavelength with the minimum cost is allocated to that particular path. This technique efficiently allocates the wavelength to the selected multiple paths and the traffic is routed to the destination using multiple paths with wavelength allocation. For simulation, NS2 simulator is used by applying the optical WDM network simulator patch. The proposed multipath RWA technique is compared with the existing RWA technique. We achieved a throughput of 12,625 packets for ten numbers of wavelengths. But the existing approach achieved a throughput of 10,189 packets only for the same numbers of wavelengths. Channel utilization is more, and delay is less compared with the existing technique. Hence, the proposed method is very efficient, since the router effectively routes the traffic within the network.
