Broadcasting is used as a building block in many MANET (Mobile Ad hoc Network) routing protocols. In addition, broadcasting is a key primitive in ad hoc networks to support group-based applications. Efficiently supporting broadcasting in multihop wireless networks is therefore important. In this paper, we compare efficient broadcasting protocols based on packet forwarding with those based on ne...

The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorithm, called do...

Software-Defined Networking (SDN) has a detailed central model that separates the data plane from control plane. The SDN controller is in charge of monitoring network security and controlling flow. OpenFlow-enabled routers switches work as packet-forwarding devices system. At first, OpenFlow forwarding like do not know how to handle packets transmitted by host. This because they have any contro...

Routing of packets in mobile ad-hoc networks with a large number of nodes or with high mobility is a very difficult task and current routing protocols do not really scale well with these scenarios. The Beacon-Less Routing Algorithm (BLR) presented in this paper is a routing protocol that makes use of location information to reduce routing overhead. However, unlike other position-based routing p...

Mobile ad hoc networks (MANETs) are a collection of mobile nodes that communicates over wireless media. Performance of MANET depends on the cooperative participation of nodes in packet forwarding. During packet forwarding from source to destination, it takes help of middle hop depending on the distance. Middle hops play different role in different times. Nodes in MANETs suffer from limited reso...

Multicast protocols traditionally require that routers store information about the delivery trees. Recently, source-routed in-packet Bloom-filter (iBF) based multicast has been proposed as a remedy to this: instead of storing state in the network, the delivery tree is encoded in the packet itself using a Bloom filter. The packets are then forwarded based on the in-packet information instead of ...

The authors propose three variants of distributed and stateless forwarding strategies for wireless sensor networks, namely greedy minimum energy consumption forwarding protocol (GMFP), lifetime maximising GMFP (LM-GMFP) and variance minimising GMFP (VAR-GMFP), which aim at maximising the network lifetime while achieving a high forwarding success rate. GMFP selects a forwarding node that minimis...

by extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. security is a serious challenge for actual implementation in wireless networks. due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
