An Optimal Routing Protocol Using a Multiverse Optimizer Algorithm for Wireless Mesh Network

Wireless networks, particularly Wireless Mesh Networks (WMNs), are undergoing a significant change as a result of wireless technology advancements and the Internet's rapid expansion. Mesh routers, which have limited mobility and serve as the foundation of WMN, are made up of mesh clients and form the core of WMNs. Mesh clients can with mesh routers to create a client mesh network. Mesh clients can be either stationary or mobile. To properly utilise the network resources of WMNs, a topology must be designed that provides the best client coverage and network connectivity. Finding the ideal answer to the WMN mesh router placement dilemma will resolve this issue MRP-WMN. Since the MRP-WMN is known to be NP-hard, approximation methods are frequently used to solve it. This is another reason we are carrying out this task. Using the Multi-Verse Optimizer algorithm, we provide a quick technique for resolving the MRP-WMN (MVO). It is also proposed to create a new objective function for the MRP-WMN that accounts for the connected client ratio and connected router ratio, two crucial performance indicators. The connected client ratio rises by an average of 16.1%, 12.5%, and 6.9% according to experiment data, when the MVO method is employed to solve the MRP-WMN problem, the path loss falls by 1.3, 0.9, and 0.6 dB when compared to the Particle Swarm Optimization (PSO) and Whale Optimization Algorithm (WOA), correspondingly

EFFICIENT SECRECY MAINTAINING CERTIFICATION SCHEME FOR VANET

Abstract VANET are one of the new promising techniques used to enable communication on roads. Here for VANETs an efficient secrecy maintaining authentication scheme is done .To detect anonymous authentication group signature is used widely used but in previous scheme it suffers from long computation delay in CRL (certificate revocation list) checking. It leads to a high message loss.so they cannot achieve the target of receiving 100 of messages per second.so HMAC is used here to avoid time consuming CRL checking and to ensure the integrity of messages before batch group authentication. To reduce authentication burden each vehicle needs to verify a small number of messages using cooperative message authentication among entities. Hence security and performance analysis shows that our scheme is more efficient in terms of authentication speed by keeping conditional privacy in VANETs. Thus the proposed scheme is analyzed through simulations in NS2 and proved to out performs the existing available techniques. Keywords-Vehicular Ad Hoc Network (VANET), CRL(Certificate Revocation List)HMAC(Hash Message Authentication Code),Cooperative Message Authentication. 1. Introduction In the advanced development of wireless communication technologies, car manufactures and telecom industries help to equip each vehicle with wireless devices. It allows vehicles to communicate with each other as well as with other vehicles network communication devices like road side units (RSU) and Trustedauthority (TA)etc. Generally a VANET consists of three components they are onboard units, Road side units and a central trusted authority. In VANET when vehicles communicate with each other and also with RSU and TA in which the attackers can easily get users private information such as identity, tracing etc. The reason is that they are not properly protected so we should design an efficiency secrecy maintaining authentication scheme for VANET. In previous scheme group signature is used for detecting unknown authentication so for which any group member allows to sign behalf of the group without reveling its real identity. So when a vehicle receives a message from unknown entity, a vehicle has to check the (certificate revocation list) CRL to avoid communicate with revoked vehicles. Also To verify the sender's group signature to check the validity of the received message. The problem here occurs is the time consuming for CRL checking because it takes 11ms to verify a message with a group signature and 9ms to check one identity in CRL. If n revoked number in CRL th number of messages verified in one second is 1000/9n+1 it is very smaller than the target of verifying 600.so we should try to overcome the delay caused by CRL checking and group signature verification to achieve rapid authentication. Thus an efficient privacy authentication scheme for VANET has been done through RSU by jointly using the techniques of distributed management, HMAC, group signature verification and cooperative authentication. First dividing the precinct into several domains so the system can run in a localized manner. Then HMAC is calculated with group key generated by the self-healing group-key generation algorithm which reduces time consuming CRL checking and ensure the integrity of messages before batch verification. Then cooperative message authentication is used to improve the message authentication scheme .By using these P.Anand Sateesh Kumar et al

Deficiency and Also Transgenic Overexpression of Timp-3 Both Lead to Compromised Bone Mass and Architecture In Vivo

Tissue inhibitor of metalloproteinases-3 (TIMP-3) regulates extracellular matrix via its inhibition of matrix metalloproteinases and membrane-bound sheddases. Timp-3 is expressed at multiple sites of extensive tissue remodelling. This extends to bone where its role, however, remains largely unresolved. In this study, we have used Micro-CT to assess bone mass and architecture, histological and histochemical evaluation to characterise the skeletal phenotype of Timp-3 KO mice and have complemented this by also examining similar indices in mice harbouring a Timp-3 transgene driven via a Col-2a-driven promoter to specifically target overexpression to chondrocytes. Our data show that Timp-3 deficiency compromises tibial bone mass and structure in both cortical and trabecular compartments, with corresponding increases in osteoclasts. Transgenic overexpression also generates defects in tibial structure predominantly in the cortical bone along the entire shaft without significant increases in osteoclasts. These alterations in cortical mass significantly compromise predicted tibial load-bearing resistance to torsion in both genotypes. Neither Timp-3 KO nor transgenic mouse growth plates are significantly affected. The impact of Timp-3 deficiency and of transgenic overexpression extends to produce modification in craniofacial bones of both endochondral and intramembranous origins. These data indicate that the levels of Timp-3 are crucial in the attainment of functionally-appropriate bone mass and architecture and that this arises from chondrogenic and osteogenic lineages
