In our previous work, we proposed a method of Message Suppression Controller (MSC) considering Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. In this paper, we evaluate the proposed MSC method for Vehicular Delay Tolerant Networking (VDTN). The simulations for two scenarios are conducted considering obstacles (buildings), where MSC embedded in Vehicles (MSCV) are present...
In previous work, we proposed a Message Suppression (MS) method for Vehicular Delay Tolerant Networking (Vehicular-DTN) considering Epidemic routing protocol. In this paper, we evaluate our proposed MS method considering three different DTN routing protocols under highly stressed environment. In order to evaluate the performance of MS method, we use Direct Delivery, Spray and Wait and Epidemic as...
In previous work, we proposed a Message Suppression (MS) method for Vehicular Delay Tolerant Networking (Vehicular-DTN) considering Epidemic routing protocol. In this paper, we evaluate our proposed MS method considering two different topologies for different DTN routing protocols.

In recent years, vehicular ad‐hoc networks (VANETs) have emerged as a unique type of mobile ad‐hoc networks. VANETs are an important component of the intelligent transportation systems. They can been utilized to guarantee road safety, avoid potential accidents and create new forms of inter‐vehicle communications. In this paper, we consider a network‐as‐a‐service architecture for VANET cloud computing...
The Delay/Disruption Tolerant Networking (DTN) aims to provide inter-operable communications with wide range of networks which have poor performance characteristics. In previous work, we proposed a message suppression method for Vehicular-DTN (VDTN) considering UDP traffic. In this paper, we evaluate the proposed method for VDTN considering TCP traffic.

By the rapid adoption of information terminals such as tablets and smart phones, people having multiple wireless communication terminals are expected to increase the access and traffic amount. In public facilities, hot spots, and university campuses, the coverage area of the wireless Access Points (APs) is limited because of high cost. Therefore, it is difficult to provide stable network connectivity...
