In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...

In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

mobile ad hoc networks (manets) are composed of mobile stations communicating through wireless links, without any fixed backbone support. in these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. tora is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it doesn’...

عدم وجود منبع تغذی دایمی برای گره های بی سیم در شبکه های موردی و محدودیت باتری های موجود باعث می شود که تنها راه برای افزایش طول مدت کارکرد این دستگاه ها صرفه جویی در مصرف انرژی باشد. یکی از راه های کاهش مصرف انرژی کم کردن زمان فعالیت واسط شبکه در گره ها است. به علت مصرف بالای این واسط ها در صورت کاهش زمان فعالیت آنها می توان میزان زیادی از انرژی باتری را برای زمان مورد نیاز ذخیره کرد. برای کاه...

In recent years, mobile ad-hoc networks have been used widely due to advances in wireless technology. These networks are formed in any environment that is needed without a fixed infrastructure or centralized management. Mobile ad-hoc networks have some characteristics and advantages such as wireless medium access, multi-hop routing, low cost development, dynamic topology and etc. In these netwo...

This paper focuses on the improvement on the performance of AODV single path routing protocol concerning the route maintenance mechanism with security. This paper presents the performance comparison of proposed protocol Secure and efficient AODV (SE-AODV) with AODV routing protocol using NS2. As the reactive routing protocols is completely different from the proactive routing protocols because ...

Multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. In this paper, a new clustering based multi path routingprotocol namely ECRR (Energy efficient Cluster based Routing algorithm for improving Reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required QoS ...

In our previous work we created a new ad hoc routing protocol MYLAR1, by modifying LAR1 routing protocol. The previous work showed that MYLAR1 routing protocol showed better performance as compared to LAR1 routing protocol in performance parameters such as: end to end delay, throughput, jitter and packets received without error. This paper discusses the comparison of MYLAR1 with other ad hoc ro...
