مجھ پہ ہے ظلم کہ ملنا بھی گوارا نہ کیا
مجھ پہ ہے ظلم کہ ملنا بھی گوارا نہ کیا
ملنا تو دور کوئی رسمی اشارہ نہ کیا
خاک تھی مجھ کو بھی اکسیر درِ جاناں کی
پر کسی نے بھی مرے درد کا چارہ نہ کیا
تھی مرے سامنے دنیا بھی حسیں، بانہیں بھی
پر ترے عشق نے کچھ اور گوارا نہ کیا
تیری ان سرمگیں آنکھوں نے بھی پھیری آنکھیں
مجھ پہ ٹھہری نہ نظر پاس ہمارا نہ کیا
دشتِ افسوس کے رہرو کو یوں چھیڑو نہ فضاؔ
تیرے کوچے سے کبھی جس نے کنارا نہ کیا

Wireless sensor networks (WSNs) have become the integral part of our daily life activities. These WSNs can utilize the unlicensed industrial, scientific and medical (ISM) band to communicate the sensed data. The ISM band has been already saturated due to overlaid deployment of WSNs and other wireless technologies such as WiFi etc. To solve this problem, WSNs have been powered up by cognitive radio (CR) capability and this rise to a new type of network called as cognitive radio sensor networks (CRSNs). In CRSNs, the unlicensed users can utilize the unlicensed as well as licensed band opportunistically. The licensed users are called the primary radio (PR) nodes where as the opportunistic unlicensed users are called as secondary or CRSN nodes. By using CR technique, CRSN nodes can utilize the spectrum holes opportunistically avoiding the interference with PR nodes. CRSNs can be deployed for number of purposes such as dynamic spectrum access to cognitive radio nodes, opportunistic channel access, overlaid deployments of multiple concurrent networks, and communication under different spectrum regulations. The potential applications of CRSNs include indoor sensing applications, multimedia applications, multi-class heterogeneous sensing applications, and real-time surveillance applications etc. All these applications require high bandwidth for communication along with avoiding CR-PR interference. In this regard, novel techniques are required which can provide large bandwidth to CRSN nodes to support their data requirements. Channel bonding (CB) is a technique to provide wide band channel by combining multiple contiguous channels. By using channel bonding (CB) technique, CRSN nodes attempt to find and combine contiguous channels to avail larger bandwidth. In this PhD thesis, we have made several contributions. Firstly, we have provided an extensive literature review of CB schemes, made meaningful classification of CB approaches and highlighted the applications of CB in various networks. Next, we have enhanced network simulator NS-2 and proposed a framework for simulating CRSNs in NS-2. Third, we have proposed an algorithm Primary Radio Activity aware Channel Bonding algorithm (PRACB) to perform channel bonding in CRSNs. We have implemented our proposed scheme PRACB in NS-2 and compared it with three schemes sample width algorithm (SWA), cognitive radio networks over white spaces (KNOWS) and AGILE. We then evaluated the performance of PRACB in different PR activity regimes. The simulation results show that our algorithm significantly avoids CR-PR harmful interference and CB in cognitive radio sensor networks (CRSNs) provides greater bandwidth to CRSN nodes. Next, we have proposed two remaining idle time aware channel bonding schemes RITCB and RITCB-IP, which select channels for CRSN nodes based on remaining idle time. In the end, we have performed comparison analysis of our schemes and shown that intelligent channel selection effectively improves the delivery ratio of CRSN nodes. In addition, some future research directions have also been highlighted at the end of this thesis.Journals by Discipline
