Intrinsic characteristics of these networks are the constant mobility and high dynamics. Furthermore, being based on vehicles, the number of network nodes tends to increase in a fast pace. All these characteristics combined with the fact that a vehicle does not always have direct communication with the core network, turns crucial the use of all available technologies and networks in the range of a vehicle, including multi-hop communications. This paper proposes an uplink manager for vehicular networks that offers multihoming, traffic differentiation and load-balancing, taking into account context-information to increase the network performance. The proposed uplink manager provides simultaneous connectivity and traffic in multiple networks and technologies, and also enables the support of vehicles with single and multi-hop connections available simultaneously. To provide such functionalities, several extensions have been performed to the control messages used in the mobility protocol to carry useful information needed to perform the uplink manager decisions. The proposed uplink manager has been tested in real networks and with real equipments. The obtained results show that it fulfils all proposed requirements, both in terms of load-balancing and traffic differentiation, without incurring any performance drop in terms of packet losses or delay.","PeriodicalId":179998,"journal":{"name":"2017 Wireless Days","volume":"110 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131544506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designing efficient forwarding scheme can reduce redundancy and collisions. Recently, we have proposed an Energy-Efficient Adaptive Forwarding Scheme (EEAFS) that uses 1-hop neighbourhood knowledge, in addition to a transmission power classification scheme to group mobile devices based on their transmission power level. Based on this classification scheme, gateway nodes that are located in the overlapping areas of different groups, are selected to forward the broadcast message. This paper has two main contributions to further improve the EEAFS. 1) Assigning a colour to each group of nodes in the network, to increases the awareness of the gateway nodes located between different groups of similar transmission power levels. 2) Developing a weight-based coordination approach between the gateway nodes to minimising the overlapping. This contributes to reducing the redundancy and collisions especially, in high dense regions. By using variable transmission power, we not only reduce the congestion, interference and conserve energy, but we also effectively involve the node's transmission power level in the forwarding decision-making process. Our solution is implemented and extensively evaluated by using ns-2. The simulation results show that the proposed broadcast technique is scalable and can significantly reduce collisions at the MAC layer by achieving up to 70 percent reduction in packet loss ratio. It also reduces end-to-end delay while consuming less energy.","PeriodicalId":179998,"journal":{"name":"2017 Wireless Days","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129603187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
