For efficient network applications, it's necessary to build security mechanisms for a secure communication. End-to-end security plays a crucial role for the communication in the network, to provide the confidentiality, the authentication and mostly the prevention from DOS attacks at high level. The main downside of the key generation and key exchange are that, the attackers might access the transmitted...
This paper discusses the cost functions of the three multicast schemes Bi-directional Tunneling, Remote Subscription and Agent Based. To developed from a probability model of engagement between any mobile network nodes in multicast group to a home agent. So the performance parameters required taken under continuous session duration constraints, taken in account the effects of nesting topology of Network...
In order to support mobile network, a management mechanism of Network Mobility Basic Support Protocol (NEMO BSP) has been standardized by Information Engineering Task Force (IETF). NEMO BSP is an extension of Mobile IPv6 (MIPv6) and inherits all the shortcomings like higher handoff latency, packet loss etc. As Network Mobility (NEMO) is engaged to manage the movement of Mobile Router (MR) and it's...
Integration of Vehicular Ad-hoc Network (VANET) and Universal Mobile Telecommunication System (UMTS) is a promising architecture for future machine-to-machine applications. This integration helps the vehicles have steady Internet connection through UMTS network and at the same time can communicate with other vehicles. However, the dead spot areas and unsuccessfully handoff processes due to the high...
In this paper we design a new protocol for confidentiality which can be applied in three scenarios. The first scenario does not need too many database modifications. We found that this protocol can offer a confident method for registration and all other messages between master/mode II devices and TV white space database (WSDB). The second scenario is tried to overcome of the delay of the first scenario...
In order for the mobile networks to stay connected to the Internet, Network Mobility (NEMO) is involved with the management of the different types of movements by mobile routers during rapid changes of the Point of Attachment (PoA). Accordingly to achieve seamless handoff with lower delay and packet loss in NEMO environment, it is very important to get better performance of mobility management protocol...
With the aim of supporting mobile network, a management mechanism of Network Mobility Basic Support Protocol (NEMO BSP) was standardized by Information Engineering Task Force (IETF) which inherits all the advantages from MIPv6. However, the NEMO BSP is inadequate to support an uninterrupted Internet connection for the MR in NEMO environment. With the aim of providing seamless Internet connectivity,...
