In mobile ad hoc network (MANET) cluster head selection is considered a gigantic challenge. In wireless sensor network LEACH\nprotocol can be used to select cluster head on the bases of energy, but it is still a dispute in mobil ad hoc networks and especially\nwhen nodes are itinerant. In this paper we proposed an efficient cluster head selection algorithm (ECHSA), for selection of the\ncluster head efficiently inMobile ad hoc networks.We evaluate our proposed algorithm through simulation in OMNet++ as well as\non test bed; we experience the result according to our assumption. For further evaluation we also compare our proposed protocol\nwith several other protocols like LEACH-C and consequences show perfection....
As technology speedily increases, diverse sensing and mobility capabilities have become readily accessible to devices\r\nand as a result mobile ad hoc networks (MANETs) are being deployed to perform a number of vital tasks. In MANET, power\r\naware is significant challenge issue to recover the communication energy efficiency at personal nodes. In this paper we\r\ncompared EEPRR with AODV, DSDV and TORA. So we proposed energy efficient power reduced routing (EEPRR), a new power\r\naware routing protocol that increases the network lifetime of MANET....
This paper takes an exploratory look on control plane signaling in a mobile cellular core network. In contrast to most contributions\nin this field, our focus does not lie on the wireless or user-oriented parts of the network, but on signaling in the core network. In\nan investigation of core network data we take a look at statistics related to GTP tunnels and their signaling. Based on the results\nthereof we propose a definition of load at the GGSN and create an initial load queuing model.We find signs of user devices putting\nburden on the core network through their behavior....
Contemporary nature of network evolution demands for simulation models which are flexible, scalable, and easily implementable.\nIn this paper, we propose a fluid based model for performance analysis of reliable high speed networks. In particular, this paper aims\nto study the dynamic relationship between congestion control algorithms and queue management schemes, in order to develop a\nbetter understanding of the causal linkages between the two.We propose a loss synchronizationmodule which is user configurable.\nWe validate our model through simulations under controlled settings. Also, we present a performance analysis to provide insights\ninto two important issues concerning 10Gbps high speed networks: (i) impact of bottleneck buffer size on the performance of\n10 Gbps high speed network and (ii) impact of level of loss synchronization on link utilization-fairness tradeoffs. The practical\nimpact of the proposed work is to provide design guidelines along with a powerful simulation tool to protocol designers and\nnetwork developers....
The recent advances of ensemble mobile environment of smart devices with embedded sensors have enabled the MANET to play a\nkey role in the smart cities as well asWSN and WMN. However, these smart devices are still limited in terms of energy, processor,\nand memory. Moreover, the efficient routing for reliable network connectivity at anytime, anywhere, and about everything is still\na challenge in multihop wireless networks. This paper evaluates the QoS and energy efficiency of three active routing protocols:\n(i) OLSRv2, a successor to OLSR, (ii) DYMO, a successor to both DSR and AODV, and (iii) MP-OLSR multipath extension to\nOLSRv2. In contrast to the related previous works which focused only on CBR traffic without considering the influence of specific\ntraffic types on the performance of routing protocols, this work focused on this area from a different perspective. It evaluates the\nperformance of three internet-based traffic types that can be used in the smart city applications:VoIP,HTTP, and FTP using different\nsimulation models. The impact of the network density, load traffic, and nodes mobility on the considered protocols was evaluated\nby considering particular performance metrics for each traffic application. Based on the results, the study concludes by presenting\nuseful recommendations for future work....
