The ANM and SDN paradigms, besides sharing a few common goals, have shown to be complementary to each other in terms of level of abstractions and expectations. In particular, we consider the Unified Management Framework (UMF) introduced in the FP7 UNIVERSELF project, which focuses on higher level self-* functionality, often assuming as given a fictional adaptation layer between such autonomics and the managed infrastructure. On the other hand, SDN architectures provide by design a uniform control substrate for the programmatic management of network resources through vendor-agnostic APIs. However, despite the popularity of flow-based control in core networks and data centers, a similar widely-adopted abstraction to that of the \"flow\" have yet to be defined for radio access and SONs. In this work we propose such a novel abstraction layer designed to realize SON programmability. The prototype Autonomic SDN (AutoSDN) controller has been integrated with UMF to self-optimize an LTE-Advanced heterogeneous network, enabling SON functions to be provided by 3rd parties and to be hot-plugged into the network.","PeriodicalId":431852,"journal":{"name":"2014 11th International Symposium on Wireless Communications Systems (ISWCS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134040948","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}

The process of minimizing the occurrence, and the consequences, of such conflicts is referred to as SON coordination. SON coordination can be achieved either by a separate entity, a SON coordinator, controlling the actions of each SON function during operation, or in the design of the SON functions as such, through a conflict free SON design. In both cases, the SON functions should be designed in a way compliant with the coordination method used. This paper proposes a number of SON design principles to apply in order to achieve this. In the case of an operational SON coordinator, SON functions should be able to deal with the possible actions that are taken by the SON coordination function in order not to worsen the problems experienced in the network. In the case of conflict free SON design the aim is at removing potential conflicts already in the design phase. The ambition of this paper is not to provide a complete set of design guidelines that address all aspects. Instead, the target is to open up the discussion on the distributed SON design principles in the community.","PeriodicalId":431852,"journal":{"name":"2014 11th International Symposium on Wireless Communications Systems (ISWCS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132397690","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}

In most cases, it is possible to have a re-deployment of new nodes in order to prolong the systems lifetime. This leads to a situation where some nodes have a low energy level while other nodes (the majority of nodes instants after the re-deployment procedure) have high energy levels. In this environments, it is clear that ancient nodes, those with low energy level, have to contend for the shared medium against the majority of high energy nodes. As such, the remaining battery life of low energy nodes would be rapidly consumed. In this paper, we propose to extend the battery life of low energy nodes by means of assigning prioritized access to the shared channel to those nodes in order to content among a low population of such nodes, while delaying the contention access of high energy nodes which can support higher number of collisions before energy depletion. This is done by studying two different transmission strategies referred to as “hard” and “soft” transmission probabilities. Results show that, a soft transmission strategy achieves better results in terms of reduced energy consumption than both the conventional protocol or a hard transmission assignment.","PeriodicalId":431852,"journal":{"name":"2014 11th International Symposium on Wireless Communications Systems (ISWCS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114219309","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}
