Packet combining scheme is a well defined simple error correction scheme with erroneous copies at the receiver. It offers higher throughput combined with ARQ protocols in networks than that of basic ARQ protocols. But packet combining scheme fails to correct errors when occur in the same bit locations of two erroneous copies. In the present work, we propose(More)
Realizing the time variant key or variable key from session to session is the key challenge in achieving perfect security [1-2]. Automatic Variable Key (AVK) is a novel approach to realize time variant key. In AVK, key is generated for use between the sender and the receiver in using a simple computation technique as proposed by Bhunia [3-5]. The AVK was(More)
DSR algorithm is applied to selects best path for communication between two nodes in a highly dynamic environment. As highly dynamic environment changes frequently, the probability of breakage of established path is high in such environment. Every time when established path breaks, a new route has to be discovered for communication between the nodes. In(More)
Aggressive Packet Combining (APC) scheme is well established for receiving correct packet in high error prone wireless link. In APC three copies of a packet are transmitted and receiver does bit wise majority decision to get the correct copy. The main research challenge in APC is that if two or more copies of the packet become erroneous at the particular(More)
Password based authentication schemes have been widely used to verify the legitimacy of a user over an insecure communication channel. A common feature among most of the published schemes is that user's identity (ID) is static in all the transaction sessions, which may leak some information about the user and can create risk of identity theft during message(More)
For reliable transport of data in wireless network, Aggressive Packet Combining (APC) scheme is well-established. APC has several limitations including throughput. Several modifications were earlier studied elsewhere for improving the throughput. The throughputs of the proposed new techniques are higher than that of APC. In this paper we propose two new(More)
Packet Reversed Packet Combining (PRPC) Scheme corrects error if occurs at same bit location. A Modified Packet Combining (MPC) Scheme corrects double or higher bit errors. Some previous studies on three schemes namely PRPC, MPC and MPC with PRPC found that they offer higher throughput over basic stop and wait ARQ protocol. We find that in practical ranges(More)
As computer networks become an essential part of our daily life, therefore, protecting the resources from unauthorized users come forward with more challenging and complicated task for the researchers. From the last few decades, many number of password-based authentication schemes have been adopted in multi-server environment to protect the resources from(More)
