In such a wireless network environment, there are two major inefficiencies: (a) load imbalance among different APs when the distribution of the location of mobile nodes is non-uniform; this might result in a situation where a lot of mobile nodes access a single AP and the rest of the APs are idle; (b) poor resource utilization; most of the mobile nodes contend for the wireless channels of APs while there are some unused and available wireless channels, which can be used to set up ad hoc groups. We propose a hybrid WLAN (H-WLAN) framework to address these two problems. First, the H-WLAN framework provides an adaptive service selection module for the mobile node to figure out a better wireless channel and the server to get its service. Second, a popularity-aware channel management module is able to integrate the ad hoc mode efficiently with the infrastructure mode by allowing mobile nodes to set up a new ad hoc group and then share their resources with other nodes within that group. The simulation results show that our H-WLAN framework can substantially (a) achieve high utilization and load balance among wireless channels with lower control overhead, and (b) provide better quality of service for the mobile nodes.","PeriodicalId":32394,"journal":{"name":"Performance","volume":"4 1","pages":"113-120"},"PeriodicalIF":0.0,"publicationDate":"2004-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74397002","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}

We propose a dynamic software management (DSM) framework to improve battery utilization, and avoid competition for limited energy resources from multiple applications. We have designed and implemented a DSM module in user space, independent of the operating system (OS), which explores quality-of-service (QoS) adaptation to reduce system energy and employs a priority-based preemption policy for multiple applications. It also employs energy macromodels for mobile applications to aid in this endeavor. By monitoring the energy supply and predicting energy demand at each QoS level, the DSM module is able to select the best possible trade-off between energy conservation and application QoS. To the best of our knowledge, this is the first energy-aware coordinated framework utilizing adaptation of mobile applications. It honors the priority desired by the user and is portable to POSIX-compliant OSs. Our experimental results for some mobile applications (video player, speech recognizer, voice-over-IP) show that this approach can meet user-specified task-oriented goals and improve battery utilization significantly. They also show that prediction of application energy demand based on energy macro-models is a key component of this framework.","PeriodicalId":32394,"journal":{"name":"Performance","volume":"30 1","pages":"306-317"},"PeriodicalIF":0.0,"publicationDate":"2004-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87164913","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}
