Performance Comparisons of Routing Protocols in Mobile Ad Hoc Networks

Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any support of central administration. Moreover, Every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. There are several familiar routing protocols like DSDV, AODV, DSR, etc...which have been proposed for providing communication among all the nodes in the network. This paper presents a performance comparison of proactive and reactive protocols DSDV, AODV and DSR based on metrics such as throughput, packet delivery ratio and average end-to-end delay by using the NS-2 simulator.Comment: 9 Pages,10 Figures, 3 Table

AN UNBALANCED AC SUPPLY THREE-PHASE DEVICE POWER CONTROLLABILITY VICTIMISATION MATHEMATICAL LOGIC CONTROLLER

This paper explains the facility controllability of 3 phase converter with associated unbalanced AC supply by mistreatment symbolic logic controller. Three-phase DC-AC power converters suffer from power oscillation and over current issues just in case of unbalanced AC supply voltage that may be caused by grid/generator faults. Existing solutions to handle these issues square measure properly choosing and dominant the positive and negative sequence currents.during this work a replacement series of management methods that utilize the zero sequence elements square measure projected to boost the facility management ability underneath this adverse condition. A fuzzy logic controller is ruled primarily based logic; it's having additional benefits than different controllers. By mistreatment fuzzy logic controller we tend to get needed output. it's finished that by introducing correct zero sequence current controls and corresponding circuit configurations, the facility converter will change additional versatile management targets, achieving higher performances within the delivered power and cargo current once affected by unbalanced AC supply

Whatsapp/Telegram Controlled Advanced Security System

Personal Security is one of the main concern when it comes to offices, personal workplace in home, bank etc. Whatsapp/Telegram controlled advanced security system’ is anintegrated security system which provides secured access to the areas where security is the main concern by providing two step verification. This system is an enhancement of the existing finger print based system. The existing finger print based system verifies the finger print of the valid user to provide authorization. But this system takes the finger prints of the user as well as captures image of that person by sensing his/her presence through sensor system and sends results of both finger prints and image to authorized person on his/her whatsapp/Telegram account. Besides this, authorized person also receives alert SMS through GSM along with Whatsapp/Telegram message. Authorized person takes the decision of access on the basis of both the results. If authorized person sends “open” from his/her Whatsapp/Telegram account, door will be opened automatically and access will be provided. If authorized person sends “unauthorized” door will remain shut and hence access will be denied. In this way system provides and ensures the two step verification to provide authorized access

PROGRESSIVE COLLAPSE ANALYSIS OF A REINFORCED CONCRETE FRAME BUILDING

ABSTRACT Progressive collapse in a structure occurs when major structural load carrying members are removed suddenly, and the remaining structural elements cannot support the weight of the building. This failure usually occurs in a domino effect and leads to a progressive collapse of the structure. The basic characteristic of progressive collapse is that the end state of destruction is disproportionately greater than the failure that initiated the collapse. This paper describes linear static analysis of a multi-storeyed building using SAP 2000 by static removal of a major structural element and nonlinear dynamic analysis by removing a single column
