The article presents a model of information flow control in a wireless sensor network (WSN). A wireless sensor network model based on hypergraph theory using network clustering is proposed. It was found that the main factor affecting the duration, speed and stability of the network is the flow of information between all nodes. The concept of piconet was introduced. Approaches for managing information flow between clusters, piconets and between them are proposed.

Simsiz sensorlar tarmoq (SST) lari ma’lumotlarni to‘plash va bazaviy stansiyaga uzatish uchun ishlatiladigan cheklangan batareya energiyasiga ega bo‘lgan sezilarli tugunlar sonini o‘z ichiga oladi. Bu yerda energiyaning katta qismi ma’lumotlarni uzatishga sarflanadi. Shuning uchun birinchi navbatda, tugunlarda energiya sarfini minimallashtirish hisobiga tarmoqning yashash muddatini maksimal darajada oshirish kerak. Bu muammoni yechish uchun ma’lumotlarni energetik samarador uzatishga erishish uchun klasterlashtirish usuli qo‘llaniladi. Klasterning bosh tuguni (BT) tanlanadi, u qolgan energiyani tejash uchun energiyani taqsimlash mexanizmidan foydalanadi va bu bilan tarmoqning yashash muddatini uzaytiradi. Turli xil mavjud usullar qo‘llaniladi, ammo har bir algoritm individual sezilarli cheklovlarga ega. Bu maqolada taklif etilgan differensial evolyusiya algoritmiga ega Sparrowni qidirish gibrid algoritmi simsiz sensorlar tarmoqlarida klaster boshini tanlash yo‘li bilan energetik samaradorlik muammosini yechish uchun mo‘ljallangan.

Simsiz sensorlar tarmoqlariga IoTni qo‘llab-quvvatlaydigan bugungi sanoat va iste’molchi ilovalarida juda katta e’tibor berilmoqda, ularda maqsadli ma’lumotlarni to‘plash uchun bir jinsli yoki turli jinsli sensorlar qo‘llaniladi. SSTlar avtonom ishlaydigan sensorli tugunlar yordamida ishlashga mo‘ljallangan, chunki ularning ilovalarini tanlash geografik jihatdan muhim. Tarmoqning yashash vaqti katta bo‘lishi uchun bunday tugunlar energiya samaradorligini saqlashi kerak. Klaster boshini tanlash SST arxitekturasida hal qiluvchi rolni o‘ynaydi u asosan tarmoqning energiya iste’molini minimallashtirishga qaratilgan. U sensorlar tugunlarini shunday guruhlarga ajratadiki, past energiya iste’moli bilan bir qatorda xizmat muddati uzaytirilgan murakkab tarmoq klasteri shakllantiriladi. LEACH sifatida ma’lum bo‘lgan klasterlashtirish usuli va uning variantlari ularning o‘xshashlariga qaraganda samaraliroq bo‘lib chiqdi. Maqolada bir nechta o‘tishlarga ega muhitda sensorlar tugunlaridan (ST) klaster bosh tuguni (BT) ga eng qisqa yo‘l marshruti bilan to‘liq bog‘langan tarmoqni yaratish uchun elektrostatik razryad algoritmidan foydalanadigan yangi to‘liq bog‘langan energetik samarador klasterlashtirish mexanizmi (FCEEC) taklif etiladi

Currently, there are plenty of devices and technologies that are used in satellite systems. One of them is IoT. IoT (Internet of Things) is a growing network of objects, devices and machines each able to communicate with the other using a wireless network to access the Internet. IoT devices have a flexible range of both wired and wireless connectivity options. IoT protocols mostly use ISM band frequencies of 4.33GHz, 915MHz, 2.4GHz to 5GHz.
