In the encoding process, a small amount of information is added into the original transmitted signal to generate the output signal for transmission, and the user at the receiver end is able to obtain both contents. In the decoding process, the added extra bits are first extracted from the received signal, and then used to recover the original signal. The scheme was examined by simulation method and its performance was measured. Error control codes were applied to the extra bits before the encoding process so that the scheme's performance can be significantly improved. The scheme was also examined by transmitting the data through an AWGN channel to observe its performance when implemented in general applications. With the proposed scheme, the existing allocated bandwidth in the broadcast channel can be utilized in a more efficient way.","PeriodicalId":178842,"journal":{"name":"Proceedings.

The network topology changes frequently due to host migration, signal interference and power outages. This makes routing maintenance challenging for routing protocol design. We present an active route maintenance protocol to prevent the existing route from disconnecting. By monitoring the status of signal strength and the stability of individual hosts, an active node that causes the route to have a weak connection actively issues a route reestablishing process in which the active host selects one of its neighbors as the candidate for partial reconstruction of the weak connection. An enhanced active route maintenance protocol is also proposed to reduce the probability of route breakage and enhance the route efficiency. Performance simulation results show that the proposed route maintenance protocol effectively reduces both the overhead and route maintenance, as well as alleviating the route-break phenomenon.","PeriodicalId":178842,"journal":{"name":"Proceedings.

The model discussed is based on the SNMPv3 structure defined in RFC 2570-2575. This model defines accounting functionality, which is a result of the growth of importance of the SNMP and its wide usage. We assume that this will be one of the steps to improve and upgrade SNMP to answer the modern requirements. The accounting mechanism is an addition to the authentication and authorization functionalities that are already implemented in SNMPv3 by using the USM (user-based security model) and VACM (view-based access control model).

But the Internet TCP/IP communication protocol was not designed to cover a mobile host, so the IP protocol should detect a mobile host that independently moves and have a moving management system to transmit the data. That is, the mobile IP protocol, must provide the mobile host with the continuous connection to the Internet. The mobile IP proposed by the IETF is efficient, but if the mobile host moves frequently and communicates with others in a specific zone, it may be inefficient. This is because there would be a delay in registering the mobile hosts and in setting up a secure tunnel in the Internet environment, and also in transmitting the data. These inefficiencies were maximized by the mobile host that has an incessant mobility. When the mobile host registered itself with the home agent, the registration cost can be reduced by using boarder router to manage the mobility within a specific zone. It enables the mobile host to detect quickly by placing an anchor FA that uses the anchor chain scheme, which is a combined pointer forwarding and caching method. Therefore, to solve the inefficiencies of the mobile IP, we suggest the border router and anchor FA to manage the mobility in the specific zone and to efficiently detect the mobile host.","PeriodicalId":178842,"journal":{"name":"Proceedings.

We compare the performance advantages of the end-to-end mobility scheme with the network-layer mobility, scheme, and prove by experiments that the end-to-end scheme, i.e. SLM, is a better solution for host mobility in many situations.","PeriodicalId":178842,"journal":{"name":"Proceedings.

In the proposed server based schemes, the dynamic link QoS state information, which is required for a QoS path computation, is implicitly maintained at the route server as it assigns or retrieves QoS paths. By maintaining the network state information this way, we may not only eliminate the overhead in exchanging network state update messages but also achieve higher routing performance. We discuss techniques for reducing the amount of processing overhead at the route server, and evaluate the performance of the proposed schemes using simulation. The simulation results show that the proposed server based QoS routing schemes may improve the routing performance compared to the distributed QoS routing schemes proposed in the literature, and the proposed processing reduction methods may significantly reduce the processing cost at the route server.","PeriodicalId":178842,"journal":{"name":"Proceedings.

MIP defines two functional entities - HA (home agent) and FA (foreign agent) - to pursue the location of mobile host and tunneling to deliver packets that are destined to the mobile node's home address. But, this tunneling has difficulties in adapting Internet service architecture - Integrated Service and Differentiated Service. Since both identify the service session as destination IP address, IP protocol number and destination port, a new different service session must be defined over the IP tunnel. For that reason, how to guarantee the QoS over IP tunnel and interoperate with end-to-end service session are key features for MIP QoS. Since MIP QoS is mostly dependent on host mobility supporting protocol, we believe that the host mobility supporting protocol must be regarded as important factor. The current host mobility supporting protocol has hierarchical architecture as micro mobility and macro mobility. So, if the MIP QoS could be viewed as the same hierarchical architecture, the better QoS guarantee might be possible. This paper specifies a hierarchical scheme, which uses not only aggregate RSVP between domain level agents, but also applies specific local policy between domain level agent and mobile host in a domain.","PeriodicalId":178842,"journal":{"name":"Proceedings.
