Therefore, RPL is the routing protocol chosen for most Internet of Things (IoT) applications. However, the RPL protocol has some open issues when the scenario includes mobile nodes. Since many IoT applications include mobility, this is an important problem to address. Node mobility does not permit the network to stabilize and because of this keep exchanging control messages. Mobility increases the packet loss because mobile nodes may leave the coverage area before transmitting the data. This problems also increase the power consumption. Another important factor affects the RPL performance. To save nodes energy, the data link layer implements a radio duty cycle. These duty cycles turn the radio off when it is not used. One common and used radio duty cycle protocol is the ContikiMAC. Changes in the frequency of the duty cycle modifies the RPL performance. This work shows how the change of radio duty cycle of ContikiMAC on a hybrid scenario, composed by fixed and mobile nodes, interferes on RPL performance. Results show that the nodes mobility degrade the metrics tested. The choice of radio duty cycle is very important to the network performance. The results show that the RPL performance is strictly dependent of the duty cycle.","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124266571","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}

Current research to accelerate the classification with hardware employing Field-programmable Gate Arrays (FPGAs) created a variety of approaches, with significant differences in terms of hardware resource requirements, memory usage, configuration update time, and power dissipation. However, there is no optimal, universal method for classification at link rate, due to inherent conflicts between large generic circuits with high resource consumption, and optimized circuits with limited versatility. Thus, current implementations have different trade-offs in terms of memory usage, resource requirements, power consumption, and flexibility. As a new approach to tackle this challenge, we present a hybrid concept that combines an highly optimized configuration-specialized and thus energy- and resource-efficient classification circuit with a generic matching circuit whose configuration can be updated quickly. The combined circuit can thus support reasonably fast configuration updates, has a low power dissipation, and can process network packets at link rate.","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134355945","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}

When a switch fails, its immediate downstream switch(es) will detect the failure. A downstream switch is protected if it has a neighbor whose path to the controller is not affected by this failure. By rerouting its traffic to this neighbor, the protected switch will bypass the failure (of its parent). On the other hand, an unprotected switch cannot bypass the failure using the local rerouting above; and the subtree rooted at the unprotected switch will be disconnected from the controller. Let the weight of an unprotected switch be the number of switches in the subtree. Then the weight of a controller tree is the total weight of all unprotected switches. In this paper, we focus on the problem of finding the minimum weight controller tree (mwCT). We first introduce a new switch protection mechanism called sibling protection. We then prove that the mwCT problem is NP-hard. To solve it, we formulate the first Integer Linear Programming (ILP). We show that the solutions obtained by an existing heuristic are far from optimal.","PeriodicalId":169489,"journal":{"name":"2017 IEEE 18th International Conference on High Performance Switching and Routing (HPSR)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127021168","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}
