Optical CDMA Network Simulator (OCNS)

Optical CDMA Wireless Multi-User Network System includes some transmitters and receivers. In this network, an Optical Orthogonal Code (OOC) is assigned to each user (Tx or Rx) to connect to its equivalent-OOC user and after synchronization between this two equivalent-OOC user, they can send and receive data to/from each other. In this project, I worked […]

Optimal Placement in Network On-Chip

Abstract: Parallel programming is emerging fast and intensive applications need more resources, so there is a huge demand for on-chip multiprocessors. Accessing L1 caches beside the cores are the fastest after registers but the size of private caches cannot increase because of design, cost and technology limits. Then split I-cache and D-cache are used with […]

Game-theoretic model to mitigate packet dropping

Abstract: Performance of routing is severely degraded when misbehaving nodes drop packets instead of properly forwarding them. In this paper, we propose a Game-Theoretic Adaptive Multipath Routing (GTAMR) protocol to detect and punish selfish or malicious nodes which try to drop information packets in routing phase and defend against collaborative attacks in which nodes try […]

Secure Multipath Adaptive Routing Protocol

Abstract Locally multipath adaptive routing (LMAR) protocol, classified as a new reactive distance vector routing protocol for MANETs is proposed in this paper. LMAR can find an ad-hoc path without selfish nodes and wormholes using a random search algorithm in polynomial-time. Also when the primary path fails, it discovers an alternative safe path if network […]
